CIMAP2
Chr 1ciliary microtubule associated protein 2
Also known as: C1orf177, LEM, LEXM
This gene encodes a ciliary and flagellar associated protein that localizes to the ciliary axoneme and is involved in ciliary motility. Mutations cause primary ciliary dyskinesia-40, an autosomal recessive disorder characterized by chronic respiratory tract infections, bronchiectasis, and situs inversus in approximately half of patients. The gene shows relatively low constraint against loss-of-function variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
