Genes affected
DYDC1 (HGNC:23460): (DPY30 domain containing 1) This gene encodes a member of a family of proteins that contains a DPY30 domain. The encoded protein is involved in acrosome formation during spermatid development. This gene locus overlaps with a closely related gene on the opposite strand. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]
DYDC2 (HGNC:23468): (DPY30 domain containing 2) This gene encodes a member of a family of proteins that contains a DPY30 domain. This gene locus overlaps with a closely related gene on the opposite strand. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2023The c.74G>A (p.R25H) alteration is located in exon 3 (coding exon 1) of the DYDC1 gene. This alteration results from a G to A substitution at nucleotide position 74, causing the arginine (R) at amino acid position 25 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
