Bazex–Dupré–Christol syndrome

Bazex–Dupré–Christol syndrome is a very rare condition inherited in an X-linked dominant fashion. Physical findings typically include follicular atrophoderma, multiple basal cell carcinomas, hypotrichosis, and hypohidrosis.[2]

This condition is inherited in an X-linked dominant manner.

Genetics

BCDS is inherited in an X-linked dominant manner. This means the defective gene responsible for the disorder is located on the X chromosome, and only one copy of the defective gene is sufficient to cause the disorder when inherited from a parent who has the disorder. Males are normally hemizygous for the X chromosome, having only one copy. As a result, X-linked dominant disorders usually show higher expressivity in males than females.

As the X chromosome is one of the sex chromosomes (the other being the Y chromosome), X-linked inheritance is determined by the gender of the parent carrying a specific gene and can often seem complex. This is because, typically, females have two copies of the X-chromosome, while males have only one copy. The difference between dominant and recessive inheritance patterns also plays a role in determining the chances of a child inheriting an X-linked disorder from their parentage.A locus of Xq24-q27 has been described.[3] However, no gene has been identified.

Diagnosis

Genetic testing--x linked dominant pattern associated with various neoplasm (eg. basal cell carcinoma)

Treatment
gollark: I chose LEN-236 because that's (some of) what my existing TBU Oxide reactor outputs.
gollark: WIP reactor with 800% efficiency and 5.8kRF/t running on LEN-236.
gollark: So how does your central thingy work?
gollark: Oh, RIGHT. That's annoying.
gollark: I'm going to design a stupidly large reactor with one fuel cell and as much as possible filled with moderators.
