Mutational landscape of DNAH1 in Chinese patients with multiple morphological abnormalities of the sperm flagella: cohort study and literature review.

ABSTRACT:

Purpose

Multiple morphological abnormalities of the sperm flagella (MMAF) are important causes of male infertility. Mutations in DNAH1 are the main causative factors proven so far. We aim to determine the mutational landscape of DNAH1 in Chinese patients with MMAF.

Methods

Forty-one Chinese patients with MMAF were enrolled and underwent a 10-gene next-generation sequencing panel screening.

Results

Only the DNAH1 gene was found to have mutations in 12 of these unrelated individuals (29%). Combining published data from two other cohorts of Chinese men with MMAF, we suggest that p.P3909fs*33, p.R868X, p.Q1518X, p.E3284K, and p.R4096L are hotspot mutations. A polymorphism-rs12163565 (G>A)- showed linkage to p.P3909fs*33, suggesting that this involved a founder effect. Fou
