Genes affected

CYLD (HGNC:2584): (CYLD lysine 63 deubiquitinase) This gene is encodes a cytoplasmic protein with three cytoskeletal-associated protein-glycine-conserved (CAP-GLY) domains that functions as a deubiquitinating enzyme. Mutations in this gene have been associated with cylindromatosis, multiple familial trichoepithelioma, and Brooke-Spiegler syndrome. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CYLD. . Gene score misZ 3.5455 (greater than the threshold 3.09). Trascript score misZ 4.7021 (greater than threshold 3.09). GenCC has associacion of gene with familial multiple trichoepithelioma, familial cylindromatosis, amyotrophic lateral sclerosis, Brooke-Spiegler syndrome, frontotemporal dementia and/or amyotrophic lateral sclerosis 8, trichoepithelioma, multiple familial, 1.

BP4

Computational evidence support a benign effect (MetaRNN=0.16377282).
