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]

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in DPY19L2 are known to be pathogenic (PMID: 22627659, 22653751). This variant has been reported in an individual affected with globozoospermia (PMID: 22653751). This variant is present in population databases (rs587777205, ExAC 0.005%). This sequence change creates a premature translational stop signal (p.Lys680*) in the DPY19L2 gene. It is expected to result in an absent or disrupted protein product. -
