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]

Variant classified as Uncertain Significance - Favor Benign. The p.Thr569Met var iant in PRDM16 has not been previously reported in individuals with cardiomyopat hy. This variant has been identified in 5/9438 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs200647136) . Threonine (Thr) at position 569 is not conserved in mammals or evolutionarily distant species, raising the possibility that a change at this position may be t olerated. Additional computational prediction tools suggest that the p.Thr569Met variant may not impact the protein, though this information is not predictive e nough to rule out pathogenicity. In summary, while the clinical significance of the p.Thr569Met variant is uncertain, these data suggest that it is more likely to be benign. -

The c.1706C>T (p.T569M) alteration is located in exon 9 (coding exon 9) of the PRDM16 gene. This alteration results from a C to T substitution at nucleotide position 1706, causing the threonine (T) at amino acid position 569 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 569 of the PRDM16 protein (p.Thr569Met). This variant is present in population databases (rs200647136, gnomAD 0.04%). 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: 426420). 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. -
