Genes affected
PRDM16 (HGNC:14000): (PR/SET domain 16) The reciprocal translocation t(1;3)(p36;q21) occurs in a subset of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). This gene is located near the 1p36.3 breakpoint and has been shown to be specifically expressed in the t(1:3)(p36,q21)-positive MDS/AML. The protein encoded by this gene is a zinc finger transcription factor and contains an N-terminal PR domain. The translocation results in the overexpression of a truncated version of this protein that lacks the PR domain, which may play an important role in the pathogenesis of MDS and AML. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

Found in a 23-year-old female with unexplained postpartum sudden cardiac arrest, along with 5 other VUSs. p.Gly513Ser (c.1537G>A) in exon 9 of the PRDM16 gene (NM_022114.3; ENST00000270722.9) Chromosome location 1:3328298 G / A Based on the information reviewed below, including the lack of case data, prevalence in population databases, and this variant's being the default in multiple other species, we classify it as Variant of Uncertain Significance (VUS), Probably Benign. The PRDM16 gene currently has no well-established disease association; however, there is preliminary evidence supporting a correlation with autosomal dominant left ventricular noncompaction (LVNC) (MedGen UID: 349005) and dilated cardiomyopathy (DCM) (OMIM: 615373). This variant has not been reported in the literature in association with disease, according to the Invitae report. This is a nonconservative amino acid change, resulting in the replacement of a nonpolar Glycine with a polar Serine. Glycine at this location is fairly well conserved across ~100 vertebrate species for which we have data, but it is instead a Serine in at least 3 mammalian species. There are no Likely Pathogenic or Pathogenic missense variants listed in ClinVar within 10 amino acids to either side. According to the Invitae report, algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant was reported in 24 individuals in the gnomAD database, which includes variant calls on ~140,000 individuals of European, African, Latino, South Asian, Ashkenazi, and East Asian descent. Overall MAF: 0.009%. Specifically, the variant was observed in 20 non-Finnish Europeans (for the highest allele frequency: 0.016%), 2 Latinos, and 2 African ancestry individuals. Invitae notes that it has an allele count higher than expected for a pathogenic variant. There is good coverage at this site. The phenotype of those individuals is not publicly available. The dataset is comprised of multiple cohorts, some of which were recruited from the general population, others were enriched for common cardiovascular disease. The curators made an effort to exclude individuals with severe pediatric diseases. -

Variant summary: PRDM16 c.1537G>A (p.Gly513Ser) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 9.3e-05 in 246486 control chromosomes, predominantly at a frequency of 0.00018 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 5 fold of the estimated maximal expected allele frequency for a pathogenic variant in PRDM16 causing Dilated Cardiomyopathy (3.6e-05), suggesting that the variant may be a polymorphism found primarily in populations of Non-Finnish European origin. c.1537G>A has been reported in the literature as a VUS in a setting of multipanel gene testing in an individual affected with Dilated Cardiomyopathy (Rieger_2019). This report does not provide unequivocal conclusions about association of the variant with Dilated Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as VUS-possibly benign. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 513 of the PRDM16 protein (p.Gly513Ser). This variant is present in population databases (rs200278862, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PRDM16-related conditions. ClinVar contains an entry for this variant (Variation ID: 241421). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
