Nonsense mutation in CFAP43 causes normal-pressure hydrocephalus with ciliary abnormalities.

ABSTRACT:

Objective

To identify genes related to normal-pressure hydrocephalus (NPH) in one Japanese family with several members with NPH.

Methods

We performed whole-exome sequencing (WES) on a Japanese family with multiple individuals with NPH and identified a candidate gene. Then we generated knockout mouse using CRISPR/Cas9 to confirm the effect of the candidate gene on the pathogenesis of hydrocephalus.

Results

In WES, we identified a loss-of-function variant in CFAP43 that segregated with the disease. CFAP43 encoding cilia- and flagella-associated protein is preferentially expressed in the testis. Recent studies have revealed that mutations in this gene cause male infertility owing to morphologic abnormalities of sperm flagella. We knocked out mouse ortholog
