Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 5P and 1B. PM2 PM5 PP2 BP4

The NM_003722.5(TP63):​c.1738T>G​(p.Ser580Ala) variant causes a missense change. The variant allele was found at a frequency of 0.0000263 in 152,216 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S580P) has been classified as Pathogenic.

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: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr3-189890874-T-C is described in ClinVar as Pathogenic. ClinVar VariationId is 6545.Status of the report is no_assertion_criteria_provided, 0 stars.
• 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.
• BP4: Computational evidence support a benign effect (MetaRNN=0.366924).
