Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2
The NM_020975.6(RET):c.3281G>A(p.Ser1094Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,236 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. S1094G) has been classified as Uncertain significance.

Submissions by phenotype
Multiple endocrine neoplasia, type 2 Uncertain:1
This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 1094 of the RET protein (p.Ser1094Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RET-related conditions. ClinVar contains an entry for this variant (Variation ID: 543722). 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. -
not provided Uncertain:1
The RET c.3281G>A (p.Ser1094Asn) variant has not been reported in individuals with RET-related conditions in the published literature. The frequency of this variant in the general population, 0.0000066 (1/152236 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.S1094N variant (also known as c.3281G>A), located in coding exon 20 of the RET gene, results from a G to A substitution at nucleotide position 3281. The serine at codon 1094 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
