Snyder-Robinson Syndrome is a rare genetic disorder that primarily affects males. It is caused by mutations in the Spermine Synthase (SMS) gene. This condition is hereditary and follows an X-linked recessive pattern of inheritance. This means that the mutated gene is located on the X chromosome, and males are more likely to be affected. Females can be carriers of the gene mutation without showing symptoms. Genetic counseling is recommended for families with a history of Snyder-Robinson Syndrome.
Snyder-Robinson Syndrome (SRS) is a rare genetic disorder that primarily affects males. It is characterized by intellectual disability, muscle and bone abnormalities, and distinctive facial features. SRS is caused by mutations in the Spermine Synthase (SMS) gene, which is located on the X chromosome.
Being an X-linked disorder, SRS follows a specific inheritance pattern. Females have two X chromosomes, while males have one X and one Y chromosome. If a female carries a mutation in one of her X chromosomes, she is considered a carrier and typically does not show symptoms of the disorder. However, there is a 50% chance that she will pass the mutated gene to her children.
In males, who have only one X chromosome, a single mutation in the SMS gene is sufficient to cause SRS. As a result, if a male inherits the mutated gene from his carrier mother, he will be affected by the syndrome. It is important to note that SRS is typically not inherited from the father, as he passes his Y chromosome to his sons.
Genetic testing can be performed to confirm a diagnosis of Snyder-Robinson Syndrome. If a family has a known history of SRS or if there are concerns about the disorder, consulting with a genetic counselor or a healthcare professional with expertise in genetics is recommended.
Understanding the hereditary nature of Snyder-Robinson Syndrome is crucial for families affected by the disorder. Genetic counseling and testing can provide valuable information about the risk of passing on the condition and help individuals make informed decisions regarding family planning.
