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]

Submissions by phenotype

not specified Uncertain:1Benign:2
Likely benign, criteria provided, single submitterclinical testingGeneDxJan 16, 2018This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 14, 2015Variant classified as Uncertain Significance - Favor Benign. The c.38-14G>A vari ant in PRDM16 has not been previously reported in individuals with cardiomyopath y, but has been identified in 0.1% (59/62964) of European chromosomes by the Exo me Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs3684099 02). This variant is located in the 3' splice region. Computational tools do not suggest an impact to splicing. However, this information is not predictive enou gh to rule out pathogenicity. In summary, while the clinical significance of the c.38-14G>A variant is uncertain, its frequency suggests that it is more likely to be benign. -
