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]

Significance: Uncertain significance

Review Status: flagged submission

Collection Method: clinical testing

A variant of uncertain significance has been identified in the PRDM16 gene. The L939V variant has not been published as a pathogenic variant or been reported as a benign variant to our knowledge. Although the L939V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties, it occurs at a position that is conserved across species. Furthermore, in silico analysis predicts this variant may be damaging to the protein structure/function. Nevertheless, ExAC reports L939V was observed in approximately 0.8% of alleles from individuals of East Asian ancestry, indicating it may be a rare benign variant in this population.Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or a rare benign variant in individuals of Asian ancestry. This result cannot be interpreted for diagnosis or used for family member screening at this time. -
