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]

GeneDx

Aug 16, 2017

A variant of uncertain significance has been identified in the PRDM16 gene. The G15S variant has not been published as pathogenic or been reported as benign to our knowledge. This variant has been observed in 3/8490 (0.04%) alleles from individuals of East Asian ancestry, and 1/8960 (0.01%) alleles from individuals of African ancestry, in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The G15S variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, this substitution occurs at a position that is not conserved across species and serine (S) is the wild-type residue at this position in multiple species. Finally, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. -
