Genes affected

ZNF175 (HGNC:12964): (zinc finger protein 175) Enables DNA-binding transcription activator activity, RNA polymerase II-specific; DNA-binding transcription repressor activity, RNA polymerase II-specific; and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II and positive regulation of transcription by RNA polymerase II. Located in cytosol; intermediate filament cytoskeleton; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.679G>T (p.V227F) alteration is located in exon 5 (coding exon 4) of the ZNF175 gene. This alteration results from a G to T substitution at nucleotide position 679, causing the valine (V) at amino acid position 227 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
