Is DSE p.Ala710Val (c.2129C>T) pathogenic?

DSE p.Ala710Val (c.2129C>T) is classified Uncertain significance in DSE (ClinVar, Multiple submitters, 3 submitters; last evaluated 2025-09-28). AlphaMissense: likely benign (0.2025); Ultra-rare (popmax 0.0506%, afr); Associated with Ehlers-Danlos syndrome, musculocontractural type 2.

What condition is associated with DSE p.Ala710Val (c.2129C>T)?

DSE p.Ala710Val (c.2129C>T) is associated with Ehlers-Danlos syndrome, musculocontractural type 2 (ClinVar).

How common is DSE p.Ala710Val (c.2129C>T) in the general population?

DSE p.Ala710Val (c.2129C>T) is ultra-rare (popmax 0.0506%, afr) (gnomAD).

How is Musculocontractural Ehlers-Danlos syndrome inherited?

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

What do computational predictors say about DSE p.Ala710Val (c.2129C>T)?

AlphaMissense predicts likely benign (score 0.2025) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
