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.

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 343 of the TP63 protein (p.Arg343Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Rapp-Hodgkin syndrome and acro-dermo-ungual-lacrimal-tooth (ADULT) syndrome and ectrodactyly, ectodermal dysplasia, and cleft lip/palate (EEC) syndrome (PMID: 10839977, 12525544, 26882220, 27028492). This variant is also known as p.Arg304Gln. ClinVar contains an entry for this variant (Variation ID: 6534). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TP63 protein function. This variant disrupts the p.Arg343 amino acid residue in TP63. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 10535733, 12525544, 19353588, 20180707, 21652629, 23355676, 24734328). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -

Reported previously in the heterozygous state, using alternate nomenclature (R304Q), in association with ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome (Ianakiev et al., 2000; van Bokhoven et al., 2001; Barrow et al., 2002; Dianzani et al., 2003; de Mollerat et al., 2003); Observed in a female who lacked ectrodactyly, thus diagnosed with Rapp-Hodgkin syndrome, and her daughter who reportedly had all of the cardinal features of EEC syndrome (Brueggemann et al., 2016); Published functional studies demonstrate that this variant abolishes p63 transcriptional activity at promoters of the KRT14, IRF6, and DSC3 genes, and impairs its intrinsic DNA binding ability (Russo et al., 2018); Not observed in large population cohorts (Lek et al., 2016); Also known as p.R304Q; This variant is associated with the following publications: (PMID: 10839977, 12161593, 14684701, 12525544, 27028492, 29130604, 32224865, 31682841, 17224651, 21652629, 29339502, 11462173, 26882220) -
