Genes affected

ZNF735 (HGNC:32466): (zinc finger protein 735) This gene encodes a kruppel-associated box-containing zinc finger protein (KRAB-ZFP). The encoded protein contains an N-terminal kruppel-associated box (KRAB) domain and nine C-terminal C2H2-type zinc finger domains. The KRAB-ZFPs represent the largest family of mammalian transcriptional repressors, which function through the recruitment of the nuclear co-factor KRAB-Associated Protein 1 (KAP1), to engage histone modifiers and induce heterochromatin formation.

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=0.08327761).

Collection Method: clinical testing

The c.275A>G (p.H92R) alteration is located in exon 4 (coding exon 4) of the ZNF735 gene. This alteration results from a A to G substitution at nucleotide position 275, causing the histidine (H) at amino acid position 92 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
