Is NGF p.Ala18Ser (c.52G>T) pathogenic?

NGF p.Ala18Ser (c.52G>T) is classified Uncertain significance in NGF (ClinVar, Single submitter, 1 submitter; last evaluated 2020-02-15). AlphaMissense: likely benign (0.1322); Absent from gnomAD v4.1; Associated with hereditary sensory and autonomic neuropathy type 5.

What condition is associated with NGF p.Ala18Ser (c.52G>T)?

NGF p.Ala18Ser (c.52G>T) is associated with hereditary sensory and autonomic neuropathy type 5 (ClinVar).

How common is NGF p.Ala18Ser (c.52G>T) in the general population?

NGF p.Ala18Ser (c.52G>T) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about NGF p.Ala18Ser (c.52G>T)?

AlphaMissense predicts likely benign (score 0.1322) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.1322	likely benign
REVEL	0.398	indeterminate
SaProt	LLR -7.08	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL is indeterminate.

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.
