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]

p.Arg582His (c.1745G>A) in Exon 9 of the PRDM16 gene (NM_022114.3) Chromosome location: 1:3328506 G / A Based on the information reviewed below, including the lack of case data, and the fact that it is 10x more common in individuals like our patient who have Asian ancestry, we classify this as a Variant of Uncertain Significance, 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 previously been reported in the literature in association with disease, according to the Invitae report. This is a conservative amino acid change, resulting in the replacement of a positively-charged Arginine with a positively-charged Histidine. Arginine at this location is poorly conserved across ~100 vertebrate species for which we have data. The adjacent residues are also poorly conserved. The Histidine variant is found as the default amino acid in at least 5 mammalian species, suggesting that this missense change does not adversely affect protein function. There are no Likely Pathogenic or Pathogenic variants currently 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 output the following: (SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). These predictions have not been confirmed by published functional studies This variant was reported in 40 individuals in the gnomAD database, which includes variant calls on ~140,000 individuals of European, African, Latino, South Asian, Ashkenazi, and East Asian descent. Specifically, the variant was observed in 27 individuals with South Asian ancestry (for the highest allele frequency: 0.09%), 7 non-Finnish Europeans, 3 East Asians, 1 Latino, and 2 â€œOtherâ€. Overall MAF 0.01%. There is also one individual with a different variant at this location: p.Arg582Cys. There is good sequencing 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. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 582 of the PRDM16 protein (p.Arg582His). This variant is present in population databases (rs529401311, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. 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: 474412). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

The c.1745G>A (p.R582H) alteration is located in exon 9 (coding exon 9) of the PRDM16 gene. This alteration results from a G to A substitution at nucleotide position 1745, causing the arginine (R) at amino acid position 582 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
