What condition is associated with GLA p.Ser176Arg (c.528T>G)?

GLA p.Ser176Arg (c.528T>G) is associated with Fabry disease (ClinVar).

How common is GLA p.Ser176Arg (c.528T>G) in the general population?

GLA p.Ser176Arg (c.528T>G) is absent from gnomAD v4.1 (gnomAD).

How is Fabry disease inherited?

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

What do computational predictors say about GLA p.Ser176Arg (c.528T>G)?
