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

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

• PM1: In a hotspot region, there are 8 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_003722.5
• PM2: Very rare variant in population databases, with high coverage
• 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, premature ovarian failure 21, limb-mammary syndrome, ectrodactyly, ectodermal dysplasia, and cleft lip-palate syndrome 3, ankyloblepharon-ectodermal defects-cleft lip/palate syndrome, EEC syndrome, split hand-foot malformation, split hand-foot malformation 4.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.895
• PP5: Variant 3-189868650-G-A is Pathogenic according to our data. Variant chr3-189868650-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 544363.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 355 of the TP63 protein (p.Asp355Asn). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of ectrodactyly–ectodermal dysplasia–cleft palate (EEC) syndrome (PMID: 36071541; Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 544363). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt TP63 function with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
