Variant summary

Our verdict is Benign. Variant got -14 ACMG points: 2P and 16B. PM5 BP4_Strong BP6_Very_Strong BS2

The NM_022114.4(PRDM16):​c.2468G>A​(p.Arg823His) variant causes a missense change. The variant allele was found at a frequency of 0.000251 in 1,524,294 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R823C) 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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• PM5: Other missense variant is known to change same aminoacid residue: Variant chr1-3412665-G-C is described in Lovd as [Likely_pathogenic].
• BP4: Computational evidence support a benign effect (MetaRNN=0.00794363).
• BP6: Variant 1-3412665-G-A is Benign according to our data. Variant chr1-3412665-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 510913.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-3412665-G-A is described in Lovd as [Likely_benign].
• BS2: High AC in GnomAd4 at 61 AD gene.
