لكلام ده معناه ان نسخه واحده من الجين المعطوب تكفي لظهور المرض يعني الطفل ميكنش حامل للمرض يسليم يا مصاب
Epidermolytic hyperkeratosis can have different inheritance patterns. About half of the cases of this condition result from new mutations in the KRT1 or KRT10 gene and occur in people with no history of the disorder in their family.
When epidermolytic hyperkeratosis is inherited, it is usually in an autosomal dominant pattern, which means one copy of the altered KRT1 or KRT10 gene in each cell is sufficient to cause the disorder.
Very rarely, epidermolytic hyperkeratosis caused by mutations in the KRT10 gene can be inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
يعني نسخه واحده كافيه لظهور المرض انا مش فاهم علشان طفرة يبقي نسخه واحده تظهر المرض ولا ايه وضحلي
