Genes affected

SPAG16 (HGNC:23225): (sperm associated antigen 16) Cilia and flagella are comprised of a microtubular backbone, the axoneme, which is organized by the basal body and surrounded by plasma membrane. SPAG16 encodes 2 major proteins that associate with the axoneme of sperm tail and the nucleus of postmeiotic germ cells, respectively (Zhang et al., 2007 [PubMed 17699735]).[supplied by OMIM, Jul 2008]

Ambry Genetics

Apr 25, 2023

The c.1103T>A (p.V368D) alteration is located in exon 11 (coding exon 11) of the SPAG16 gene. This alteration results from a T to A substitution at nucleotide position 1103, causing the valine (V) at amino acid position 368 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
