Affected people are usually born to unaffected parents. Parents of affected people are usually asymptomatic carriers. It affects either sex. After the birth of an affected child, each subsequent child has a 25% chance of being affected (assuming that both parents are heterozygous carriers). X-linked dominant Autosomal recessive Y-linked X-linked recessive
