Is ASPDH p.Leu88Pro (c.263T>C) pathogenic?

ASPDH p.Leu88Pro (c.263T>C) is classified Uncertain significance in ASPDH (ClinVar, Single submitter, 1 submitter; last evaluated 2024-02-28). AlphaMissense: likely pathogenic (0.8843); Very rare (popmax 0.00167%, amr).

How common is ASPDH p.Leu88Pro (c.263T>C) in the general population?

ASPDH p.Leu88Pro (c.263T>C) is very rare (popmax 0.00167%, amr) (gnomAD).

What do computational predictors say about ASPDH p.Leu88Pro (c.263T>C)?

AlphaMissense predicts likely pathogenic (score 0.8843) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.8843	likely pathogenic · top 7% in ASPDH
REVEL	0.567	indeterminate
SaProt	LLR -13.16	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL makes no call.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — 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.
