Variant summary: PIK3CA c.1633G>A (p.Glu545Lys) results in a conservative amino acid change located in the Phosphoinositide 3-kinase, accessory (PIK) domain (IPR001263) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 247990 control chromosomes (gnomAD). c.1633G>A has been reported in the literature in multiple individuals affected with PIK3CA-Associated Segmental Overgrowth spectrum disorders (example: Baptiste-Riviere_2013, DGama_2016, Kuentz_2017, Mirzaa_2016, Yates_2018). In several of these patients, the variant was described as a mosaic mutation. In addition, somatic occurrence of this variant was also reported in a number tumors including but not limited to Breast Cancer and Seborrheic Keratosis (example: Hafner_2010, Juric_2019). These data indicate that the variant is very likely to be associated with disease. Several reports suggest that this variant is a hot-spot mutation. Consistent with these reports in functional studies, the variant was found to have greater lipid kinase activities. In vitro cell line studies expressing the variant also demonstrate constitutive activation of downstream components of PI3K signaling pathway. In transformation assays using NIH 3T3 cells, the variant induced more foci than the wild-type (Ikenoue_2005). Several ClinVar submitters (evaluation after 2014) cite the variant as pathogenic/likely pathogenic in the context of germline and somatic origin. Based on the evidence outlined above, the variant was classified as pathogenic.

A somatic mutation is present within the PIK3CA (Exon 10) gene in the DNA extracted from tissue. Gain-of-function (usually somatic mosaic) mutations in PIK3CA are associated with PIK3CA-Related Overgrowth Spectrum (PROS) and the PIK3CA c.1633G>A; p.(Glu545Lys) (Chr3:g.178936091G>A) variant has previously been reported in patients with PROS, CLOVES syndrome, fibroadipose hyperplasia and isolated macrodactyly (PMID: 28151489, 29661094) The PIK3CA c.1633G>A; p.(Glu545Lys) variant results in a p110 alpha-helical domain substitution (PMID:26637981), activates AKT, disrupts normal EC-characteristic monolayer morphology as visualized by phase-contrast microscopy, results in loss of ECM fibronectin, and strongly downregulates ANGPT2 and PDGF-B mRNA expression as measured by real-time quantitative PCR. Plasminogen system-components are also somewhat dysregulated by the variant PIK3CA c.1633G>A; p.(Glu545Lys) (PMID:26637981). The variant is located in a mutational hot spot and/or critical and well-established functional domain (e.g., active site of an enzyme) without benign variation: using strength Strong because Hot-spot of length 17 amino-acids has 21 non-VUS missense/in-frame variants (21 pathogenic and 0 benign), pathogenicity = 100.0%, qualifies as a dense hot-spot. The variant is absent from controls in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium: GnomAD exomes allele count = 1 is less than 5 for gene PIK3CA (good gnomAD exomes coverage = 42.7) and the variant is not found in gnomAD genomes (good gnomAD genomes coverage = 31.4). The variant is a missense change at an amino acid residue where a different missense change determined to be pathogenic has been seen before: alternative variants chr3:178936091G>C (Glu545Gln); chr3:178936092A>C (Glu545Ala); chr3:178936092A>G (Glu545Gly); chr3:178936092A>T (Glu545Val); chr3:178936093G>C (Glu545Asp) and chr3:178936093G>T (Glu545Asp) are classified Pathogenic. The variant is a missense variant in a gene that has a low rate of benign missense variation and in which missense variants are a common mechanism of disease: 246 out of 254 non-VUS missense variants in gene PIK3CA are pathogenic = 96.9% which is more than threshold of 51.0%, and 259 out of 587 clinically reported variants in gene PIK3CA are pathogenic = 44.1% which is more than threshold of 12.0%. Multiple lines of computational evidence support a deleterious effect on the gene or gene product: Pathogenic computational verdict based on 11 pathogenic predictions from BayesDel_addAF, DANN, DEOGEN2, EIGEN, FATHMM-MKL, LIST-S2, M-CAP, MVP, MutationTaster, PrimateAI and SIFT vs 1 benign prediction from MutationAssessor (PMID:30376034). The variant is annotated in Clinvar as a pathogenic variant associated with PIK3CA-related overgrowth spectrum (https://www.ncbi.nlm.nih.gov/clinvar/variation/13655/). Based on a modification of the ACMG Guidelines (PMID:25741868, 25880439), the PIK3CA c.1633G>A; p.(Glu545Lys) variant is classified as a pathogenic variant. (less)

This variant has previously been reported in several unrelated individuals with PIK3CA-related segmental overgrowth syndrome (PMID: 31536475, PMID: 25681199, PMID: 29985963, NBK153722 and others). The p.E545K variant substitutes the glutamic acid at position 545 with lysine within the helical domain of the PIK3CA protein. This is an activating mutation that results in ligand-independent activation of the PI3K-AKT-mTOR pathway and increased proliferation in vitro (PMID: 26627007). (less)

In 9 breast tumors (114480), 1 epithelial ovarian tumor (167000), and 2 colorectal tumors (114500) from a series of 284 primary human tumors, Campbell et al. (2004) identified a 1633G-A transition in exon 9 of the PIK3CA gene, resulting in a glu545-to-lys (E545K) substitution. Lee et al. (2005) identified the E545K mutation in tumor tissue from 2 breast cancers, 3 gastric cancers (137215), and 1 nonsmall cell lung cancer (211980). Hafner et al. (2007) identified a heterozygous somatic E545K mutation in 2 seborrheic keratosis lesions (182000). The authors emphasized that this is a benign lesion and noted that the same mutation had been observed in cancerous lesions. In an individual with megalencephaly-capillary-malformation-polymicrogyria syndrome (MCAP; 602501), Riviere et al. (2012) identified the mosaic E545K mutation in the PIK3CA gene. Lee et al. (2012) performed whole-exome sequencing on brain and peripheral blood DNA from 5 patients with hemimegalencephaly (HME) and identified the E545K missense mutation in the PIK3CA gene. The mutant allele was absent in blood but present in the brain, with a mutation burden of 36.6%. Lee et al. (2012) screened for this mutation in 15 other patients with HME and identified the E545K variant in 3, each with a mutation burden of about 30%. One of these individuals had hypertrophic regions in the right hand and foot. (less)
