Invitae RCV000206045 SCV000259848 uncertain significance Multiple endocrine neoplasia, type 2 2022-10-20 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 778 of the RET protein (p.Val778Ile). This variant is present in population databases (rs75686697, gnomAD 0.006%). This missense change has been observed in individual(s) with familial medullary thyroid cancer and bilateral renal aplasia (PMID: 11732489, 12016484, 18252215, 30927507). ClinVar contains an entry for this variant (Variation ID: 13955). An algorithm developed specifically for the RET gene suggests that this missense change is likely to be tolerated (PMID: 21479187). Experimental studies have shown that this missense change affects RET function (PMID: 18252215). 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.
Ambry Genetics RCV000562190 SCV000674786 likely benign Hereditary cancer-predisposing syndrome 2020-02-26 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: 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.
Illumina Laboratory Services, Illumina RCV001105833 SCV001262839 uncertain significance Hirschsprung disease, susceptibility to, 1 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Laboratory Services, Illumina RCV001105834 SCV001262840 uncertain significance Multiple endocrine neoplasia 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Laboratory Services, Illumina RCV000014983 SCV001265261 uncertain significance Renal hypodysplasia/aplasia 1 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Laboratory Services, Illumina RCV001108067 SCV001265262 uncertain significance Pheochromocytoma 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
