3-M syndrome is an autosomal recessive primordial growth disorder characterized by pre- and post-natal growth restriction, facial dysmorphism and radiological abnormalities. Mutations in the gene CUL7 have been previously shown to cause 3-M syndrome. CUL7 is a member of the cullin family of E3 ubiquitin ligases involved in targeted protein degradation.We identified a large cohort of 3-M syndrome patients who did not carry CUL7 mutations but...

Background: Lower cut-offs in TSH screening have doubled the incidence of congenital hypothyroidism (CH), particularly cases with an eutopically-located Gland-in-situ (GIS). Although mutations in known dyshormonogenesis genes, or the thyrotropin-stimulating hormone receptor (TSHR) may underlie such cases, these genes have not previously been screened comprehensively in a GIS CH cohort.Study design: We evaluated the relative contribution and mole...
