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 -2 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.2805128).
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000256 (39/152310) while in subpopulation AMR AF = 0.00248 (38/15306). AF 95% confidence interval is 0.00186. There are 0 homozygotes in GnomAd4. There are 25 alleles in the male GnomAd4 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

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 130792). This variant has not been reported in the literature in individuals affected with ZNF335-related conditions. This variant is present in population databases (rs530390392, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 440 of the ZNF335 protein (p.Arg440Leu).

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1319G>T (p.R440L) alteration is located in exon 8 (coding exon 7) of the ZNF335 gene. This alteration results from a G to T substitution at nucleotide position 1319, causing the arginine (R) at amino acid position 440 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
