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.

The 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. -
