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 submitterclinical testingCenter for Genomics, Ann and Robert H. Lurie Children's Hospital of ChicagoMar 30, 2021PRDM16 NM_022114.3 exon 9 p.Gly817Ser (c.2449G>A): This variant has not been reported in the literature but is present in 0.2% (41/18334) of African alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/1-3329210-G-A). This variant is present in ClinVar (Variation ID:241425). Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineAug 14, 2016Variant classified as Uncertain Significance - Favor Benign. The p.Gly817Ser var iant in PRDM16 has not been previously reported in individuals with cardiomyopat hy, but has been identified in 0.2% (6/2466) of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs375308440 ). Computational prediction tools and conservation analysis suggest that the p.G ly817Ser variant may impact the protein, though this information is not predicti ve enough to determine pathogenicity. In summary, while the clinical significanc e of the p.Gly817Ser variant is uncertain, its frequency suggests that it is mor e likely to be benign. -
