Genes affected

JUP (HGNC:6207): (junction plakoglobin) This gene encodes a major cytoplasmic protein which is the only known constituent common to submembranous plaques of both desmosomes and intermediate junctions. This protein forms distinct complexes with cadherins and desmosomal cadherins and is a member of the catenin family since it contains a distinct repeating amino acid motif called the armadillo repeat. Mutation in this gene has been associated with Naxos disease. Alternative splicing occurs in this gene; however, not all transcripts have been fully described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.802

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000239 (35/1461802) while in subpopulation SAS AF= 0.000394 (34/86256). AF 95% confidence interval is 0.00029. There are 0 homozygotes in gnomad4_exome. There are 27 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces asparagine with isoleucine at codon 309 of the JUP protein (p.Asn309Ile). The asparagine residue is moderately conserved and there is a large physicochemical difference between asparagine and isoleucine. This variant is present in population databases (rs140606359, ExAC 0.04%). This variant has not been reported in the literature in individuals with JUP-related conditions. 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
