Is COL5A2 p.Pro965= (c.2895A>G) pathogenic?

COL5A2 p.Pro965= (c.2895A>G) is classified Likely benign in COL5A2 (ClinVar, Multiple submitters, 8 submitters; last evaluated 2026-02-03). Ultra-rare (popmax 0.037%, nfe); Associated with Ehlers-Danlos syndrome, classic type, 1.

What condition is associated with COL5A2 p.Pro965= (c.2895A>G)?

COL5A2 p.Pro965= (c.2895A>G) is associated with Ehlers-Danlos syndrome, classic type, 1, Ehlers-Danlos syndrome, classic type, 2, familial thoracic aortic aneurysm and aortic dissection (ClinVar).

How common is COL5A2 p.Pro965= (c.2895A>G) in the general population?

COL5A2 p.Pro965= (c.2895A>G) is ultra-rare (popmax 0.037%, nfe) (gnomAD).

How is Classical Ehlers-Danlos syndrome inherited?

Typically Autosomal dominant (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.
