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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.1667T>A (p.L556Q) alteration is located in exon 18 (coding exon 18) of the DPY19L2 gene. This alteration results from a T to A substitution at nucleotide position 1667, causing the leucine (L) at amino acid position 556 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
