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

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.54).
• BP6: Variant 17-41755432-C-T is Benign according to our data. Variant chr17-41755432-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 384420.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000095 (25/263132) while in subpopulation MID AF= 0.00149 (2/1346). AF 95% confidence interval is 0.000264. There are 0 homozygotes in gnomad4_exome. There are 13 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck.
