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.2064A>T (p.K688N) alteration is located in exon 21 (coding exon 21) of the DPY19L2 gene. This alteration results from a A to T substitution at nucleotide position 2064, causing the lysine (K) at amino acid position 688 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
