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.

Ambry Genetics

Nov 07, 2022

The c.1136T>C (p.M379T) alteration is located in exon 13 (coding exon 13) of the MORC1 gene. This alteration results from a T to C substitution at nucleotide position 1136, causing the methionine (M) at amino acid position 379 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
