Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_022114.4(PRDM16):c.2809C>A(p.Pro937Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000403 in 1,613,292 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 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. P937A) has been classified as Uncertain significance.

Left ventricular noncompaction 8 Uncertain:2
PRDM16 NM_022114.3 exon 11 p.Pro937Thr (c.2809C>A): This variant has not been reported in the literature but is present in 0.06% (16/24086) of African alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/1-3334509-C-A). This variant is present in ClinVar (Variation ID:573517). Evolutionary conservation suggests that this variant may impact the protein; computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 937 of the PRDM16 protein (p.Pro937Thr). This variant is present in population databases (rs374972823, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with PRDM16-related conditions. ClinVar contains an entry for this variant (Variation ID: 573517). 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 tolerated. 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. -
not provided Uncertain:1
Has not been previously published as pathogenic or benign to our knowledge; In silico analysis indicates that this missense variant does not alter protein structure/function -
