Variant summary
Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4_StrongBP6BS2
The NM_022114.4(PRDM16):c.2281G>A(p.Ala761Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00048 in 1,613,086 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. A761A) has been classified as Likely benign.

PRDM16: BP4, BS1 -
Has not been previously published in association with cardiomyopathy to our knowledge; Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID# 406239; Landrum et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 28050010) -
Left ventricular noncompaction 8 Uncertain:1
This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 761 of the PRDM16 protein (p.Ala761Thr). This variant is present in population databases (rs200947814, 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: 406239). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
