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

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.036017597).

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000154 (225/1461584) while in subpopulation MID AF = 0.00329 (19/5768). AF 95% confidence interval is 0.00216. There are 1 homozygotes in GnomAdExome4. There are 109 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1336 of the ZNF335 protein (p.Val1336Ile). This variant is present in population databases (rs372687838, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with ZNF335-related conditions. ClinVar contains an entry for this variant (Variation ID: 437341). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
