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.529A>G (p.T177A) alteration is located in exon 5 (coding exon 5) of the MORC3 gene. This alteration results from a A to G substitution at nucleotide position 529, causing the threonine (T) at amino acid position 177 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
