Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3
The NM_021619.3(PRDM12):c.440G>A(p.Arg147His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000967 in 1,614,012 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R147C) has been classified as Uncertain significance.

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
PM2 -
Congenital insensitivity to pain-hypohidrosis syndrome Uncertain:1
This sequence change replaces arginine with histidine at codon 147 of the PRDM12 protein (p.Arg147His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs139807684, ExAC 0.006%). This variant has not been reported in the literature in individuals affected with PRDM12-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -
Inborn genetic diseases Uncertain:1
The c.440G>A (p.R147H) alteration is located in exon 3 (coding exon 3) of the PRDM12 gene. This alteration results from a G to A substitution at nucleotide position 440, causing the arginine (R) at amino acid position 147 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
