Genes affected

ZMAT1 (HGNC:29377): (zinc finger matrin-type 1) This gene encodes a protein containing Cys2-His2 (C2H2)-type zinc fingers, which are similar to those found in the nuclear matrix protein matrin 3. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]

ZMAT1 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.05527246).

The c.1034C>G (p.S345C) alteration is located in exon 7 (coding exon 6) of the ZMAT1 gene. This alteration results from a C to G substitution at nucleotide position 1034, causing the serine (S) at amino acid position 345 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
