KLHL40
Chr 3ARkelch like family member 40
Also known as: KBTBD5, NEM8, SRYP, SYRP
The protein contains BACK, BTB/POZ, and Kelch repeat domains and localizes to the cytoplasm, though its exact cellular function remains unknown. Mutations cause nemaline myopathy with autosomal recessive inheritance. The predicted gain-of-function mechanism suggests that pathogenic variants likely alter normal protein function rather than cause loss of function.
Definitive — sufficient evidence for diagnostic panels
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
