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.

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0103 - Dominant negative, loss of function and gain of function are known mechanisms of disease in this gene. Dominant negative is associated with ectrodactyly, ectodermal dysplasia, and cleft lip/palate syndrome 3 (MIM#604292), limb-mammary syndrome (MIM#603543) and ankyloblepharon‑ectodermal defects‑cleft lip/palate syndrome. While gain of function is associated with ADULT syndrome (MIM#103285), and loss of function is likely associated with orofacial cleft 8 (MIM#618149) (PMIDs: 20556892, 32476291, 29620206). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0115 - Variants in this gene are known to have variable expressivity. TP63-related conditions are known to have wide phenotypic variability even among members of the same family (PMIDs: 20556892, 32476291, 29620206). (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to tryptophan. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v3) (2 heterozygotes, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0600 - Variant is located in the annotated P53 DNA-binding domain (DECIPHER). (I) 0703 - Another missense variant comparable to the one identified in this case has moderate previous evidence for pathogenicity. p.(Arg243Gln) has been classified as pathogenic by several clinical laboratories in ClinVar. (SP) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been classified as pathogenic by multiple clinical laboratories in ClinVar and has been observed in individuals with EEC3, SHFM, and ADULT syndrome in the literature (PMIDs: 32476291, 20556892). (SP) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed) (by trio analysis).

This missense change has been observed in individual(s) with a TP63-related disease, including ectrodactyly-ectodermal dysplasia-cleft (EEC) syndrome and ADULT syndrome, in some of whom it was found de novo (PMID: 10535733, 18792980, 21078104, 22607287, 23355676). In at least one individual the variant was observed to be de novo. For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg243 amino acid residue in TP63. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12525544, 28293528, 29620206). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Experimental studies have shown that this missense change affects TP63 function (PMID: 18626511, 23355676, 23463580). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt TP63 protein function. ClinVar contains an entry for this variant (Variation ID: 6527). This variant is also known as p.Arg204Trp. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 243 of the TP63 protein (p.Arg243Trp). -

The variant is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.95; 3Cnet: 0.99). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000006527). A different missense change at the same codon (p.Arg243Gln) has been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000006528). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -
