Genes affected
MORC1 (HGNC:7198): (MORC family CW-type zinc finger 1) This gene encodes the human homolog of mouse morc and like the mouse protein it is testis-specific. Mouse studies support a testis-specific function since only male knockout mice are infertile; infertility is the only apparent defect. These studies further support a role for this protein early in spermatogenesis, possibly by affecting entry into apoptosis because testis from knockout mice show greatly increased numbers of apoptotic cells.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.2348A>G (p.D783G) alteration is located in exon 24 (coding exon 24) of the MORC1 gene. This alteration results from a A to G substitution at nucleotide position 2348, causing the aspartic acid (D) at amino acid position 783 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
