Genes affected

DPY19L2 (HGNC:19414): (dpy-19 like 2) The protein encoded by this gene belongs to the dpy-19 family. It is highly expressed in testis, and is required for sperm head elongation and acrosome formation during spermatogenesis. Mutations in this gene are associated with an infertility disorder, spermatogenic failure type 9 (SPGF9). [provided by RefSeq, Dec 2011]

The c.1838G>A (p.G613E) alteration is located in exon 19 (coding exon 19) of the DPY19L2 gene. This alteration results from a G to A substitution at nucleotide position 1838, causing the glycine (G) at amino acid position 613 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
