Novel MEIOB variants cause primary ovarian insufficiency and non-obstructive azoospermia.

ABSTRACT: Background: Infertility is a global health concern. MEIOB has been found to be associated with premature ovarian insufficiency (POI) and non-obstructive azoospermia (NOA), but its variants have not been reported in Chinese patients. The aim of this study was to identify the genetic aetiology of POI or NOA in three Han Chinese families. Methods: Whole-exome sequencing (WES) was used to identify candidate pathogenic variants in three consanguineous Chinese infertile families with POI or NOA. Sanger sequencing was performed to validate these variants in the proband of family I and her affected family members. In vitro functional analyses were performed to confirm the effects of these variants. Results: Two novel homozygous frameshift variants (c.258_259del a
