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=0.13844883).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.40C>T (p.P14S) alteration is located in exon 4 (coding exon 1) of the CYLD gene. This alteration results from a C to T substitution at nucleotide position 40, causing the proline (P) at amino acid position 14 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
