What condition is associated with EDA p.Asp265Glu (c.795T>A)?

EDA p.Asp265Glu (c.795T>A) is associated with X-linked hypohidrotic ectodermal dysplasia (ClinVar).

How common is EDA p.Asp265Glu (c.795T>A) in the general population?

EDA p.Asp265Glu (c.795T>A) is absent from gnomAD v4.1 (gnomAD).

How is Hypohidrotic ectodermal dysplasia inherited?

Typically Autosomal dominant, Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about EDA p.Asp265Glu (c.795T>A)?
