Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_022114.4(PRDM16):c.867G>A(p.Met289Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000343 in 1,458,406 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M289T) 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]

Variant classified as Uncertain Significance - Favor Benign. The p.Met289Ile var iant in PRDM16 has not been previously reported in individuals with cardiomyopat hy, but has been identified in 3/64670 European chromosomes by the Exome Aggrega tion Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs375991356). Methi onine (Met) at position 289 is not conserved in evolution and 1 mammal (pig) and >10 fish species carry an isoleucine (Ile) at this position, raising the possib ility that this change may be tolerated. In summary, while the clinical signific ance of the p.Met289Ile variant is uncertain, the presence of the variant amino acid in other species suggests that it is more likely to be benign. -
