Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4BP6
The NM_020975.6(RET):c.3256G>A(p.Gly1086Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,461,866 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G1086A) has been classified as Uncertain significance.

Submissions by phenotype
Multiple endocrine neoplasia, type 2 Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 31, 2022 | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1086 of the RET protein (p.Gly1086Arg). This variant is present in population databases (rs778452896, gnomAD 0.03%). 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: 568473). 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. - |

Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 03, 2023 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
