Is NF2 p.Arg358Ser (c.1074G>C) pathogenic?

NF2 p.Arg358Ser (c.1074G>C) is classified Uncertain significance in NF2 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-05-07). AlphaMissense: likely pathogenic (0.7192); Very rare (popmax 0.00891%, eas); Associated with NF2-related schwannomatosis.

What condition is associated with NF2 p.Arg358Ser (c.1074G>C)?

NF2 p.Arg358Ser (c.1074G>C) is associated with NF2-related schwannomatosis (ClinVar).

How common is NF2 p.Arg358Ser (c.1074G>C) in the general population?

NF2 p.Arg358Ser (c.1074G>C) is very rare (popmax 0.00891%, eas) (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.Arg358Ser (c.1074G>C)?

AlphaMissense predicts likely pathogenic (score 0.7192) — an in-silico prediction, not a clinical call.

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.
