Is MYO7A p.Leu1836Pro (c.5507T>C) pathogenic?

MYO7A p.Leu1836Pro (c.5507T>C) is classified Conflicting classifications of pathogenicity in MYO7A (ClinVar, Conflicting submitters, 3 submitters; last evaluated 2025-07-31). AlphaMissense: likely pathogenic (0.9997); Very rare (popmax 0.000171%, nfe); Associated with Usher syndrome type 1.

What condition is associated with MYO7A p.Leu1836Pro (c.5507T>C)?

MYO7A p.Leu1836Pro (c.5507T>C) is associated with Usher syndrome type 1, autosomal recessive nonsyndromic hearing loss 2 (ClinVar).

How common is MYO7A p.Leu1836Pro (c.5507T>C) in the general population?

MYO7A p.Leu1836Pro (c.5507T>C) is very rare (popmax 0.000171%, nfe) (gnomAD).

How is Usher syndrome inherited?

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

What do computational predictors say about MYO7A p.Leu1836Pro (c.5507T>C)?

AlphaMissense predicts likely pathogenic (score 0.9997) — 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.
