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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2024The c.2244G>T (p.Q748H) alteration is located in exon 22 (coding exon 22) of the DPY19L2 gene. This alteration results from a G to T substitution at nucleotide position 2244, causing the glutamine (Q) at amino acid position 748 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
