We report on a German girl with congenital hypothyroidism due to a mutation in the thyroid peroxidase (TPO) gene who had elevated serum levels of thyroglobulin during periods of hyperthyrotropinemia.
A molecular analysis and long-term follow-up of two siblings with severe congenital hypothyroidism carrying the IVS30+1G>T intronic thyroglobulin mutation.
The objective of this study is to analyze the recurrence of the p.R277X/p.R1511X compound heterozygous mutation in the TG gene in two unrelated families (one Argentinian and another Brazilian) with congenital hypothyroidism, goiter and impairment of TG synthesis.

Clinical case seminar: metastatic follicular thyroid carcinoma arising from congenital goiter as a result of a novel splice donor site mutation in the thyroglobulin gene.
Thyroglobulin abnormality is a rare cause of congenital hypothyroidism and only a limited number of mutations in the thyroglobulin gene have been reported.
Low serum thyroglobulin in the proband and his older brother and parental consanguinity was mostly compatible with a thyroglobulin defective synthesis and secretion as the cause of CH and fetal goiter.
A new case of congenital goiter with hypothyroidism caused by a homozygous p.R277X mutation in the exon 7 of the thyroglobulin gene: a mutational hot spot could explain the recurrence of this mutation.
We have studied UPR development in two similar ERSDs, human congenital goiter caused by the C1264R and C1996S mutations in the thyroglobulin (Tg) gene and non-goitrous congenital hypothyroidism in rdw dwarf rats determined by the G2320RTg mutation.
Two distinct compound heterozygous constellations (R277X/IVS34-1G>C and R277X/R1511X) in the thyroglobulin (TG) gene in affected individuals of a Brazilian kindred with congenital goiter and defective TG synthesis.
Thyroid scans, serum thyroglobulin measurements, and free T4 measurements using equilibrium dialysis or 2-step immunoassay methods can identify thyroid hormone-binding protein defects and simplify the diagnosis and treatment of infants with CH.
This is the first time that a loss of function mutation of the TSH receptor is described in a patient with severe congenital hypothyroidism and absent circulating thyroglobulin due to TSH unresponsiveness and the first time that an inactivating mutation of the TSH receptor is described in the first extracellular loop.
Two novel cysteine substitutions (C1263R and C1995S) of thyroglobulin cause a defect in intracellular transport of thyroglobulin in patients with congenital goiter and the variant type of adenomatous goiter.
Autosomal recessive inheritance of mutations of the thyroid peroxidase and thyroglobulin genes has been described in some patients with congenital hypothyroidism (CH) and a family history of CH.
Inherited as an autosomal recessive trait, deficient Tg causes congenital hypothyroidism in newborns that, if untreated, results in goiter along with serious cognitive and growth defects.
Evidence for the segregation of three different mutated alleles of the thyroglobulin gene in a Brazilian family with congenital goiter and hypothyroidism.
