Illumina Laboratory Services, Illumina RCV001159943 SCV001321696 uncertain significance Iodotyrosyl coupling defect 2018-05-17 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Fulgent Genetics, Fulgent Genetics RCV002491465 SCV002800743 uncertain significance Iodotyrosyl coupling defect; Autoimmune thyroid disease, susceptibility to, 3 2021-09-23 criteria provided, single submitter clinical testing
Ambry Genetics RCV002558509 SCV003570117 uncertain significance Inborn genetic diseases 2021-09-16 criteria provided, single submitter clinical testing The c.993G>C (p.Q331H) alteration is located in exon 8 (coding exon 8) of the TG gene. This alteration results from a G to C substitution at nucleotide position 993, causing the glutamine (Q) at amino acid position 331 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
