Genes affected

TG (HGNC:11764): (thyroglobulin) Thyroglobulin (Tg) is a glycoprotein homodimer produced predominantly by the thryroid gland. It acts as a substrate for the synthesis of thyroxine and triiodothyronine as well as the storage of the inactive forms of thyroid hormone and iodine. Thyroglobulin is secreted from the endoplasmic reticulum to its site of iodination, and subsequent thyroxine biosynthesis, in the follicular lumen. Mutations in this gene cause thyroid dyshormonogenesis, manifested as goiter, and are associated with moderate to severe congenital hypothyroidism. Polymorphisms in this gene are associated with susceptibility to autoimmune thyroid diseases (AITD) such as Graves disease and Hashimoto thryoiditis. [provided by RefSeq, Nov 2009]

Variant summary: TG c.7123G>A (p.Gly2375Arg) results in a non-conservative amino acid change located in the Carboxylesterase, type B domain (IPR002018) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2e-05 in 249726 control chromosomes (gnomAD). c.7123G>A has been reported in the literature in individuals affected with congenital hypothyroidism (e.g. Hishinuma_2005, 2006, Vasudevan_2017, Long_2018, Oliver-Petit_2021). These data indicate that the variant is likely to be associated with disease. Publications report experimental evidence evaluating an impact on protein function, finding that the variant results in defective intracellular transport and incomplete glycosylation processing (Kanou_2007, De Jaco_2012). The following publications have been ascertained in the context of this evaluation (PMID: 16187918, 16720658, 17244789, 30022773, 34248839, 23035660, 28620499). ClinVar contains an entry for this variant (Variation ID: 12703). Based on the evidence outlined above, the variant was classified as pathogenic. -
