Genes affected

ZNF41 (HGNC:13107): (zinc finger protein 41) This gene encodes a protein that contains KRAB-A and KRAB-B domains multiple zinc finger DNA binding motifs and finger linking regions characteristic of the Kruppel family. An initial study suggested that this gene may be associated with X-linked cognitive disability, but a later study has called this finding into question (PMID:23871722).[provided by RefSeq, Apr 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.0819968).

The c.2332A>T (p.S778C) alteration is located in exon 5 (coding exon 4) of the ZNF41 gene. This alteration results from a A to T substitution at nucleotide position 2332, causing the serine (S) at amino acid position 778 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
