Is MYO7A p.Val10Ala (c.29T>C) pathogenic?

MYO7A p.Val10Ala (c.29T>C) is classified Conflicting classifications of pathogenicity in MYO7A (ClinVar, Conflicting submitters, 6 submitters; last evaluated 2024-05-29). AlphaMissense: likely pathogenic (0.9064); Very rare (popmax 8.49e-05%, nfe); Associated with MYO7A-related disorder.

What condition is associated with MYO7A p.Val10Ala (c.29T>C)?

MYO7A p.Val10Ala (c.29T>C) is associated with MYO7A-related disorder, Usher syndrome type 1, autosomal recessive nonsyndromic hearing loss 2 (ClinVar).

How common is MYO7A p.Val10Ala (c.29T>C) in the general population?

MYO7A p.Val10Ala (c.29T>C) is very rare (popmax 8.49e-05%, nfe) (gnomAD).

What do computational predictors say about MYO7A p.Val10Ala (c.29T>C)?

AlphaMissense predicts likely pathogenic (score 0.9064) — an in-silico prediction, not a clinical call.

Ashkenazi Jewish shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.

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.
