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.Asn161Asp var iant in PRDM16 has not been previously reported in individuals with cardiomyopat hy, but has been identified in 0.13% (13/9750) of African chromosomes by the Exo me Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs3746641 41). Computational prediction tools and conservation analysis suggest that the p .Asn161Asp variant may not impact the protein, though this information is not pr edictive enough to rule out pathogenicity. In summary, while the clinical signif icance of the p.Asn161Asp variant is uncertain, these data suggest that it is mo re likely to be benign. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.481A>G (p.N161D) alteration is located in exon 4 (coding exon 4) of the PRDM16 gene. This alteration results from a A to G substitution at nucleotide position 481, causing the asparagine (N) at amino acid position 161 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
