EBP p.His76Asp (c.226C>G) is classified Conflicting classifications of pathogenicity in EBP (ClinVar, Conflicting submitters, 2 submitters; last evaluated 2025-09-25). AlphaMissense: likely pathogenic (0.9545); Absent from gnomAD v4.1; Associated with X-linked chondrodysplasia punctata 2.

What condition is associated with EBP p.His76Asp (c.226C>G)?

EBP p.His76Asp (c.226C>G) is associated with X-linked chondrodysplasia punctata 2 (ClinVar).

How common is EBP p.His76Asp (c.226C>G) in the general population?

EBP p.His76Asp (c.226C>G) is absent from gnomAD v4.1 (gnomAD).

How is X-linked dominant chondrodysplasia punctata inherited?

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

What do computational predictors say about EBP p.His76Asp (c.226C>G)?

AlphaMissense predicts likely pathogenic (score 0.9545) — an in-silico prediction, not a clinical call.
