Genes affected

TP63 (HGNC:15979): (tumor protein p63) This gene encodes a member of the p53 family of transcription factors. The functional domains of p53 family proteins include an N-terminal transactivation domain, a central DNA-binding domain and an oligomerization domain. Alternative splicing of this gene and the use of alternative promoters results in multiple transcript variants encoding different isoforms that vary in their functional properties. These isoforms function during skin development and maintenance, adult stem/progenitor cell regulation, heart development and premature aging. Some isoforms have been found to protect the germline by eliminating oocytes or testicular germ cells that have suffered DNA damage. Mutations in this gene are associated with ectodermal dysplasia, and cleft lip/palate syndrome 3 (EEC3); split-hand/foot malformation 4 (SHFM4); ankyloblepharon-ectodermal defects-cleft lip/palate; ADULT syndrome (acro-dermato-ungual-lacrimal-tooth); limb-mammary syndrome; Rap-Hodgkin syndrome (RHS); and orofacial cleft 8.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PP2

Missense variant in the TP63 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 73 curated pathogenic missense variants (we use a threshold of 10). The gene has 15 curated benign missense variants. Gene score misZ: 2.2077 (below the threshold of 3.09). Trascript score misZ: 3.5096 (above the threshold of 3.09). GenCC associations: The gene is linked to Rapp-Hodgkin syndrome, ADULT syndrome, split hand-foot malformation 4, limb-mammary syndrome, premature ovarian failure 21, split hand-foot malformation, ankyloblepharon-ectodermal defects-cleft lip/palate syndrome, EEC syndrome, ectrodactyly, ectodermal dysplasia, and cleft lip-palate syndrome 3.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 97 of the TP63 protein (p.Arg97Cys). This variant is present in population databases (rs121908848, gnomAD 0.003%). This missense change has been observed in individual(s) with isolated ectrodactyly (PMID: 15736220). ClinVar contains an entry for this variant (Variation ID: 6549). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) did not meet the statistical confidence thresholds required to predict the impact of this variant on TP63 function. 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. -
