Is NF2 p.Asp201His (c.601G>C) pathogenic?

NF2 p.Asp201His (c.601G>C) is classified Uncertain significance in NF2 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-09-17). AlphaMissense: likely pathogenic (0.9809); Very rare (popmax 0.00133%, afr); Associated with NF2-related schwannomatosis.

What condition is associated with NF2 p.Asp201His (c.601G>C)?

NF2 p.Asp201His (c.601G>C) is associated with NF2-related schwannomatosis (ClinVar).

How common is NF2 p.Asp201His (c.601G>C) in the general population?

NF2 p.Asp201His (c.601G>C) is very rare (popmax 0.00133%, afr) (gnomAD).

How is Full NF2-related schwannomatosis inherited?

Typically Autosomal dominant (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about NF2 p.Asp201His (c.601G>C)?

AlphaMissense predicts likely pathogenic (score 0.9809) — an in-silico prediction, not a clinical 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.
