ESRP1
Chr 8ARepithelial splicing regulatory protein 1
Also known as: DFNB109, RBM35A, RMB35A
ESRP1 encodes an mRNA splicing factor that regulates the formation of epithelial cell-specific isoforms and controls splicing of genes involved in inner ear development and auditory hair cell differentiation. Mutations cause autosomal recessive deafness (DFNB109). The gene is highly constrained against loss-of-function variants, suggesting that complete loss of function is likely pathogenic.
Primary Disease Associations & Inheritance
Limited evidence — not for standalone diagnostic reporting
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Moderately missense-constrained (top ~2.5%)
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
