Is DSE p.Met918Val (c.2752A>G) pathogenic?

DSE p.Met918Val (c.2752A>G) is classified Uncertain significance in DSE (ClinVar, Multiple submitters, 2 submitters; last evaluated 2026-02-01). AlphaMissense: likely benign (0.0985); Very rare (popmax 0.00935%, afr); Associated with Ehlers-Danlos syndrome, musculocontractural type 2.

What condition is associated with DSE p.Met918Val (c.2752A>G)?

DSE p.Met918Val (c.2752A>G) is associated with Ehlers-Danlos syndrome, musculocontractural type 2 (ClinVar).

How common is DSE p.Met918Val (c.2752A>G) in the general population?

DSE p.Met918Val (c.2752A>G) is very rare (popmax 0.00935%, 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.Met918Val (c.2752A>G)?

AlphaMissense predicts likely benign (score 0.0985) — 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.
