Genes affected

MORC3 (HGNC:23572): (MORC family CW-type zinc finger 3) This gene encodes a protein that localizes to the nuclear matrix and forms nuclear bodies via an ATP-dependent mechanism. The protein is predicted to have coiled-coil and zinc finger domains and has RNA binding activity. Alternative splicing produces multiple transcript variants encoding distinct isoforms.

The c.1888T>C (p.S630P) alteration is located in exon 15 (coding exon 15) of the MORC3 gene. This alteration results from a T to C substitution at nucleotide position 1888, causing the serine (S) at amino acid position 630 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
