Is DSE p.Thr77Met (c.230C>T) pathogenic?

DSE p.Thr77Met (c.230C>T) is classified Uncertain significance in DSE (ClinVar, Multiple submitters, 3 submitters; last evaluated 2026-06-02). AlphaMissense: likely benign (0.0948); Very rare (popmax 0.00439%, sas); Associated with Inborn genetic diseases.

What condition is associated with DSE p.Thr77Met (c.230C>T)?

DSE p.Thr77Met (c.230C>T) is associated with Inborn genetic diseases, Ehlers-Danlos syndrome, musculocontractural type 2 (ClinVar).

How common is DSE p.Thr77Met (c.230C>T) in the general population?

DSE p.Thr77Met (c.230C>T) is very rare (popmax 0.00439%, sas) (gnomAD).

What do computational predictors say about DSE p.Thr77Met (c.230C>T)?

AlphaMissense predicts likely benign (score 0.0948) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0948	likely benign
REVEL	0.062	moderately benign-leaning
SaProt	LLR -8.14	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

Overall

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.
