Genes affected

ZNF335 (HGNC:15807): (zinc finger protein 335) The protein encoded by this gene enhances transcriptional activation by ligand-bound nuclear hormone receptors. However, it does this not by direct interaction with the receptor, but by direct interaction with the nuclear hormone receptor transcriptional coactivator NRC. The encoded protein may function by altering local chromatin structure. [provided by RefSeq, Jul 2008]

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=0.23253918).

The c.3913G>A (p.A1305T) alteration is located in exon 28 (coding exon 27) of the ZNF335 gene. This alteration results from a G to A substitution at nucleotide position 3913, causing the alanine (A) at amino acid position 1305 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
