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:criteria provided, single submitter
Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The p.Pro929His var iant in PRDM16 has not been previously identified in individuals with cardiomyop athy, but has been identified in 0.2% (15/9670) of African chromosomes by the Ex ome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs145632 008). Computational prediction tools and conservation analysis suggest that the variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, while the clinical significance of the p.Pro929His variant is uncertain, its frequency suggests that it is more likely to be benign. -

Left ventricular noncompaction 8 Uncertain:1

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with histidine, which is basic and polar, at codon 929 of the PRDM16 protein (p.Pro929His). This variant is present in population databases (rs145632008, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (PMID: 30847666). ClinVar contains an entry for this variant (Variation ID: 229165). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
