Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS2

The NM_022114.4(PRDM16):​c.2290G>A​(p.Val764Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00165 in 1,613,312 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V764G) has been classified as Uncertain significance.

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]

The p.Val764Met variant in PRDM16 is classified as benign because it has been id entified in 0.2% (257/126116) of European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org/). Additionally, computationa l prediction tools and conservation analysis suggest that the p.Val764Met varian t may not impact the protein. ACMG/AMP Criteria applied: BA1, BP4. -

The c.2290G>A (p.V764M) alteration is located in exon 9 (coding exon 9) of the PRDM16 gene. This alteration results from a G to A substitution at nucleotide position 2290, causing the valine (V) at amino acid position 764 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
