A new variant of spondylometaphyseal dysplasia with autosomal dominant mode of inheritance.

abstract：BACKGROUND:Four genetic causes of isolated congenital central hypothyroidism (CeH) have been identified, but many cases remain unexplained. We hypothesised the existence of other genetic causes of CeH with a Mendelian inheritance pattern. METHODS:We performed exome sequencing in two families with unexplained isolated ...
