6 Jewish hereditary diseases that might surprise you!

The diseases that transfer from one generation to the next are called hereditary diseases. Jewish hereditary diseases are diseases that are common among the Jewish community because they have a unique history and genetic makeup. So that’s why they have some specific traits which are responsible for these disorders. These diseases are not specific to the Jewish community they can affect individuals from any background but these are more common in the Jewish community so these are called Jewish hereditary diseases.

The main reason behind Jewish hereditary diseases is that the Jewish communities married within their population for generations which increases the ratio of mutations among their populations. This genetic mutation causes Jewish hereditary diseases that are more common in the individual of Jewish as compared to the general population.

 there are so many diseases that have a genetic basis but these are not population-specific like hereditary blood diseaseshereditary heart diseaseshereditary autoimmune diseaseshereditary brain diseaseshereditary kidney diseaseslupus hereditary backgroundvitiligo hereditary disease, and hereditary lung diseases. in our previous blogs, we also discuss the details of the transition mechanism of hereditary diseases and the positive role of spreading awareness of hereditary diseases

What Are Hereditary Diseases

Definition and Characteristics

Due to the abnormalities or mutations of any individual’s DNA hereditary diseases occur which are also known as genetic diseases or genetic disorders. this genetic material means DNA passes to the next generations through genetic inheritance. These genetic conditions can affect any function or structure of the individual like it can affect physical, biochemical, or metabolic processes. Hereditary diseases can cause different conditions which vary from common to severe these conditions appear in babies at the time of birth or appear later in life.

Key characteristics of hereditary diseases include:

Inheritance: Hereditary diseases are typically passed down from parents to their offspring. In the sperm cells of males and egg cells of females, these mutations are present and transferred to the new incoming generation through fertilization.

Mendelian Inheritance: Many hereditary diseases follow Mendelian inheritance patterns, which are based on principles identified by Gregor Mendel. Autosomal recessive, autosomal dominant, and X-linked inheritance are these patterns.

Genetic Mutation: genetic mutation is a change in the sequence of DNA that causes hereditary diseases.

These mutations can disrupt the normal functioning of the gene product (usually a protein), leading to abnormal biological processes or functions.

Familial Patterns: Often, these diseases exhibit familial patterns, meaning they occur more frequently in certain families or populations due to shared genetic ancestry.

Variable Expressivity: Hereditary diseases can vary in their severity and presentation, even among individuals with the same genetic mutation. Factors such as genetic modifiers and environmental influences can contribute to this variability.

How Hereditary Diseases Are Passed Down

Hereditary diseases are passed down through the transmission of genetic information from one generation to the next. The process involves the following steps:

Parental Inheritance: The genetic mutation responsible for the hereditary disease is present in one or both of the parents’ DNA.

Formation of Germ Cells: In the parents, genetic information is stored in their germ cells (sperm and egg cells). Half of the normal number of chromosomes are present in germ cells and when both germ cells combine at fertilization the resulting offspring complete their number of chromosomes half from the egg and half from the sperm.

Fertilization: The zygote is the result of fertilization, fertilzation occurs when the sperm cell of the father fertilizes the egg cell of the mother in sexual reproduction. This newly formed zygote develops and becomes an embryo and this embryo becomes a full-grown individual.

Inheritance: The genetic information from both parents combines in the offspring. If one of the parents has a genetic mutation in his or her genes which are responsible for the hereditary disease there is a chance of transfer of that mutation into the child.

Role of Genetics in Hereditary Diseases

Genes are segments of DNA that contain instructions for the production of specific proteins or molecules necessary for normal bodily functions. Mutations in genes can disrupt these instructions, leading to the production of abnormal or nonfunctional proteins.

Causative Mutations: specific mutations in the genetic material are responsible for the disease in new individuals. These mutations can be transferred to a child from one or both parents.

Gene Function:  the basic function of the gene is to produce or encode a specific protein that performs a structural or functional role. Due to the mutation in genes time non-functional proteins are produced in the body which cause hereditary disease. Sometimes the mutation may result in the no production of any important protein.

Genetic Testing: the mutations that are responsible for hereditary disease are easily identified with the help of genetic testing. Genetic testing helps the patient and his family to make informed decisions and prevention from hereditary diseases.

Jewish Hereditary Diseases Overview: Common Conditions

Within the Jewish population, several hereditary diseases have a higher prevalence due to a combination of genetic factors and shared ancestry. Some most common diseases in the Jewish community are given below.

Tay-Sachs Disease

Description: a neurodegenerative disorder that is caused by the deficiency of an enzyme known as hexosaminidase A. The major effect of this disease is on the central nervous system.

Symptoms: Symptoms frequently emerge in infancy and worsen quickly, resulting in developmental regression, loss of motor abilities, seizures, and eventually paralysis. Children with Tay-Sachs typically do not live beyond early childhood.

Gaucher Disease

Description: Gaucher disease is an inherited metabolic disorder characterized by the accumulation of a fatty substance called glucocerebroside in various organs, particularly the spleen, liver, and bones.

Symptoms: An enlarged spleen and liver, anemia, pain in bones, and a higher risk of fractures are some symptoms of Gaucher disease. There are different forms of Gaucher disease, and symptoms vary based on the type.

BRCA Mutations:

Description: BRCA is a common mutation in the Jewish community but this mutation can affect any population. In this disease, BRCA1 and BRCA2 genes are involved which increases the risk of breast cancer and ovarian cancer.

Symptoms: BRCA mutation carriers have a considerably increased chance of getting breast and ovarian cancer. Breast cancer can strike at an earlier age and be more aggressive in these people.

Cystic Fibrosis

Description:  the respiratory, digestive, and reproductive systems can be affected by cystic fibrosis and hereditary disease. It is caused by mutations in the CFTR gene.

Symptoms: Side effects incorporate thick bodily fluid creation prompting lung diseases, stomach-related issues, hunger, and, in serious cases, respiratory disappointment. While it’s not elite to the Jewish populace, explicit changes are more normal among Ashkenazi Jews.

Canavan Disease

Description: Canavan sickness is an uncommon neurological problem described by the breakdown of white matter in the mind. It is caused by mutations in the ASPA gene.

Symptoms: Side effects regularly become obvious in the early outset and incorporate formative deferral, muscle shortcomings, and loss of coordinated abilities. Seizures and vision problems may also occur.

Familial Dysautonomia (Riley-Day Syndrome)

Description: Familial dysautonomia is a hereditary disorder that affects the autonomic nervous system. It is caused by mutations in the IKBKAP gene.

Symptoms: Symptoms include difficulty swallowing, lack of tears, difficulty regulating body temperature, and sensory abnormalities. This condition primarily affects the Ashkenazi Jewish population.

Bloom Syndrome

Description: Bloom syndrome is a rare genetic disorder associated with short stature, photosensitivity, and a predisposition to cancer.

Symptoms: Bloom syndrome patients are often shorter in stature than their classmates and may experience skin rashes when exposed to sunshine. They are also at an increased risk of various cancers.

Genetics and the Jewish Population:

Due to some genetic historical and geographical factors, the risk of Jewish hereditary diseases has increased in the Jewish community.

Understanding these factors is essential for grasping the unique challenges faced by Jewish individuals in managing their genetic health.

Genetic Basis of Hereditary Diseases

Founder Effect: Many Jewish communities, particularly Ashkenazi Jews of Eastern European descent, have experienced a “founder effect.” This occurs when a small group of founders establishes a new population, and the limited genetic diversity among the founders can lead to a higher prevalence of certain genetic mutations within the community. 

Endogamy: Historically, Jewish communities often practiced endogamy, which means marrying within the same religious or ethnic group. While this practice has maintained cultural and religious continuity, it has also contributed to the preservation and concentration of specific genetic mutations within Jewish populations.

Bottleneck Events: Jewish populations have faced historical events such as persecution, migrations, and the Holocaust that have led to genetic bottlenecks. These events reduced the genetic diversity within these populations, potentially increasing the prevalence of certain diseases.

Historical and Geographical Factors

Ashkenazi Jews: Ashkenazi Jews, in particular, have a higher risk of specific hereditary diseases due to their historical isolation in Eastern Europe and the founder effects. 

Sephardic and Mizrahi Jews: While Ashkenazi Jews are more widely studied in the context of hereditary diseases, Sephardic and Mizrahi Jewish communities also have their unique genetic risks. Historical migrations and geographic isolation have contributed to distinct genetic profiles within these communities.

Population Isolates: Some Jewish communities, such as those in Iran and Yemen, lived in relative isolation, leading to distinct genetic profiles and hereditary disease risks specific to those regions.

Importance of Genetic Testing and Counseling

Early Detection: Genetic testing and counseling play a vital role in identifying individuals at risk of hereditary diseases within Jewish communities. Early detection allows for proactive management and intervention to mitigate the impact of these diseases.

Informed Family Planning: Knowledge of one’s genetic risk empowers individuals and couples to make informed decisions about family planning. They can consider options such as preconception carrier screening, in vitro fertilization (IVF) with pre-implantation genetic diagnosis (PGD), or adoption.

Support and Education: Genetic counseling provides support and education to individuals and families dealing with hereditary diseases. It helps them navigate the emotional and practical aspects of living with or at risk of these conditions.

Research and Progress: Genetic testing also contributes to ongoing research into hereditary diseases, leading to advancements in treatments and potential cures.

Stress and Anxiety: Guardians of kids with genetic sicknesses might confront ongoing pressure and uneasiness, stressing over their kid’s prosperity, future, and personal satisfaction. The uncertainty surrounding the progression of the disease can be emotionally draining.

Stigmatization: Impacted people might experience belittling or segregation because of their condition, which can prompt sensations of disconnection and low confidence.

Depression: The profound cost of dealing with a genetic illness can add to despondency, in the impacted person as well as in parental figures and relatives.

Social Impact:

Family Dynamics: Hereditary diseases can strain family relationships, as they require significant caregiving responsibilities. Siblings may experience feelings of neglect or jealousy, while parents may face challenges balancing the needs of their affected child with those of their other children.

Financial Strain: The costs associated with managing hereditary diseases, including medical treatments, therapies, and assistive devices, can place a significant financial burden on families.

Social Isolation: Families with impacted individuals might encounter social segregation because of the requests to provide care, the requirement for particular clinical consideration, or the hesitance of others to draw in people with genetic illnesses.

Educational and Career Challenges: Genetic illnesses can affect a person’s instructive achievement and vocation possibilities, prompting limits in their social and monetary doors.

Challenges in Close-Knit Communities:

Genetic Risk Awareness: In close-knit communities, awareness of genetic risk can be both a blessing and a challenge. While it promotes genetic testing and awareness, it may also create anxiety and stigma around individuals or families who are carriers or affected by hereditary diseases.

Support Networks: Close-knit communities often have strong support networks that can provide emotional and practical assistance to affected families. However, these networks may also inadvertently perpetuate stigma or pressure to conform to community norms.

Privacy and Disclosure: Balancing the desire for privacy with the need to disclose genetic risk information can be particularly challenging in small communities, where news and information spread quickly.

Personal Stories and Testimonials:

  • Sharing individual stories and tributes from people and families impacted by innate illnesses can give a strong and interesting viewpoint on the effect of these circumstances.

Education and Counseling: Information sessions and genetic counseling are provided to individuals and couples to help them understand the importance of testing and the implications of their results.

Carrier Screening: Carrier screening tests are conducted to identify individuals who carry one copy of a mutated gene associated with a hereditary disease. These individuals are usually asymptomatic but can pass the mutation to their children if both parents are carriers.

Community Outreach: Outreach endeavors might incorporate studios, courses, and organizations with medical care suppliers to guarantee admittance to hereditary testing administrations.

Access to Testing: Genetic testing is made more accessible to community members through screening events, clinics, or partnerships with healthcare facilities.

Privacy and Confidentiality: Measures are in place to maintain the privacy and confidentiality of individuals undergoing testing, addressing concerns about stigma or discrimination.

Benefits of Preconception Genetic Testing

Preconception genetic testing is a proactive approach that allows individuals or couples to assess their genetic risk before starting a family. Some key benefits include:

Informed Family Planning: Couples can settle on informed conclusions about family arranging given their hereditary gamble profiles. This might incorporate deciding to imagine normally, chasing after in vitro treatment (IVF) with pre-implantation hereditary analysis (PGD), or taking into account reception.

Reduced Risk: If both partners are carriers of the same hereditary disease, they can take steps to reduce the risk of having an affected child, such as using assisted reproductive technologies with genetic screening of embryos.

Peace of Mind: Knowing their genetic risk status can provide peace of mind to individuals and couples, alleviating anxiety about the possibility of passing on hereditary diseases to their children.
