Genes affected

RNF216 (HGNC:21698): (ring finger protein 216) This gene encodes a cytoplasmic protein which specifically colocalizes and interacts with the serine/threonine protein kinase, receptor-interacting protein (RIP). Zinc finger domains of the encoded protein are required for its interaction with RIP and for inhibition of TNF- and IL1-induced NF-kappa B activation pathways. The encoded protein may also function as an E3 ubiquitin-protein ligase which accepts ubiquitin from E2 ubiquitin-conjugating enzymes and transfers it to substrates. Several alternatively spliced transcript variants have been described for this locus but the full-length natures of only some are known. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

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=0.40380463).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000301 (44/1461760) while in subpopulation AMR AF= 0.000402 (18/44722).

The c.2662G>A (p.V888M) alteration is located in exon 17 (coding exon 16) of the RNF216 gene. This alteration results from a G to A substitution at nucleotide position 2662, causing the valine (V) at amino acid position 888 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 1345630). This variant has not been reported in the literature in individuals affected with RNF216-related conditions. This variant is present in population databases (rs760106512, gnomAD 0.04%). This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 888 of the RNF216 protein (p.Val888Met). -
