Is NLN p.Ser587Phe (c.1760C>T) pathogenic?

NLN p.Ser587Phe (c.1760C>T) is classified Uncertain significance in NLN (ClinVar, Single submitter, 1 submitter; last evaluated 2025-07-01). AlphaMissense: likely benign (0.1522); Very rare (popmax 0.00133%, afr).

How common is NLN p.Ser587Phe (c.1760C>T) in the general population?

NLN p.Ser587Phe (c.1760C>T) is very rare (popmax 0.00133%, afr) (gnomAD).

What do computational predictors say about NLN p.Ser587Phe (c.1760C>T)?

AlphaMissense predicts likely benign (score 0.1522) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1522	likely benign
REVEL	0.167	moderately benign-leaning
SaProt	LLR -9.82	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.
