This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one parent with the condition.
Inheritance of a specific disease, condition, or trait depends on the type of chromosome affected (autosomal or sex chromosome) whether the trait is is dominant or recessive. A single, abnormal gene on one of the first 22 non-sex chromosomes from either parent can cause autosomal disorder.Dominant inheritance means an abnormal gene from one parent is capable of causing disease even though the matching gene from the other parent is normal.The abnormal gene dominates the pair of genes. single, abnormal gene on one of the first 22 non-sex chromosomes from either parent can cause autosomal disorder. Dominant inheritance means an abnormal gene from one parent is capable of causing disease even though the matching gene from the other parent is normal. The abnormal gene dominates the pair of genes.
