Multiple Sulfatase Deficiency (MSD) is a rare genetic disorder that is inherited in an autosomal recessive manner. This means that both parents must carry a copy of the mutated gene for their child to be affected. MSD is caused by mutations in the SUMF1 gene, which is responsible for producing an enzyme necessary for breaking down certain molecules in the body. Individuals with MSD inherit two copies of the mutated gene, leading to a deficiency in multiple sulfatase enzymes.
Multiple Sulfatase Deficiency (MSD) is a rare genetic disorder that affects the body's ability to break down certain molecules called sulfatides. This condition is caused by mutations in the SUMF1 gene, which provides instructions for producing an enzyme called sulfatase-modifying factor 1. Without this enzyme, sulfatases in the body cannot function properly, leading to the accumulation of sulfatides in various tissues and organs.
MSD is inherited in an autosomal recessive manner, which means that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disorder. If both parents carry one copy of the mutated gene, they have a 25% chance of having a child with MSD in each pregnancy.
It is important to note that carriers of a single copy of the mutated gene do not typically show symptoms of MSD. However, they have a 50% chance of passing the mutated gene to their children. Genetic testing can be performed to determine carrier status and assess the risk of having a child with MSD.
Due to the hereditary nature of MSD, it is crucial for individuals with a family history of the disorder to seek genetic counseling before planning a pregnancy. Genetic counselors can provide information about the risks, inheritance patterns, and available testing options.
