STRC Gene (Stereocilin)

TL;DR: STRC (chr15q15.3) encodes stereocilin — outer hair cell attachment protein. ~6kb coding = too big for single AAV. Misha: compound heterozygous, one pathogenic + one VUS (E1659A, under reclassification). Treatment path: dual-vector AAV gene therapy.

Located on chromosome 15q15.3. Encodes stereocilin — a protein forming the tectorial membrane attachment crowns on outer hair cell (OHC) stereocilia. Essential for mechanoelectrical transduction efficiency.

Size: ~6 kb coding sequence. Too large for single AAV vector (requires dual-vector approach).

Misha: Compound heterozygous STRC variants (one pathogenic, one VUS E1659A). The VUS is under reclassification via AlphaFold3 structural analysis.
