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]

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Sep 20, 2022	The PRDM16 c.109G>A; p.Glu37Lys variant (rs369539275), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 576283). This variant is found in the general population with an overall allele frequency of 0.003% (9/278766 alleles) in the Genome Aggregation Database. The glutamic acid at codon 37 is moderately conserved, but computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.182). Due to limited information, the clinical significance of the PRDM16 variant is uncertain at this time. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	May 29, 2020	Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID# 576283; Landrum et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function -

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 37 of the PRDM16 protein (p.Glu37Lys). This variant is present in population databases (rs369539275, 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: 576283). 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. -
