Is DSE p.Ala295= (c.885A>C) pathogenic?

DSE p.Ala295= (c.885A>C) is classified Likely benign in DSE (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-01-28). Very rare (popmax 0.00668%, eas); Associated with Ehlers-Danlos syndrome, musculocontractural type 2.

What condition is associated with DSE p.Ala295= (c.885A>C)?

DSE p.Ala295= (c.885A>C) is associated with Ehlers-Danlos syndrome, musculocontractural type 2 (ClinVar).

How common is DSE p.Ala295= (c.885A>C) in the general population?

DSE p.Ala295= (c.885A>C) is very rare (popmax 0.00668%, eas) (gnomAD).

How is Musculocontractural Ehlers-Danlos syndrome inherited?

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

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
