Genes affected

ZNF408 (HGNC:20041): (zinc finger protein 408) The protein encoded by this gene contains ten tandem zinc fingers and an N-terminal SET domain, so it is likely a DNA binding protein that interacts with other proteins. In adults, the encoded protein is expressed most highly in retina. Consequently, defects in this gene have been associated with familial exudative vitreoretinopathy (FEVR) and retinitis pigmentosa (RP). [provided by RefSeq, Dec 2016]

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=0.019229054).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000661 (96/1452930) while in subpopulation SAS AF = 0.00108 (93/86256). AF 95% confidence interval is 0.000901. There are 1 homozygotes in GnomAdExome4. There are 67 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 617 of the ZNF408 protein (p.Thr617Asn). This variant is present in population databases (rs547169524, gnomAD 0.1%). This missense change has been observed in individual(s) with familial exudative vitreoretinopathy (PMID: 27316669). ClinVar contains an entry for this variant (Variation ID: 183059). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
