| Popis: | Objectives The normal development of the pituitary gland requires multiple induction signals and transcription factors encoded by more than 30 genes, including OTX2. OTX2 mutations have been described with eye abnormalities and variable congenital hypopituitarism, but rarely with hypopituitarism without ocular manifestations. Case presentation We report a girl with hypopituitarism associated with pituitary hypoplasia and pituitary stalk atrophy, without ocular manifestations. NGS revealed a novel heterozygous mutation in OTX2 c.426dupC:p.(Ser143Leufs*2). Conclusions Mutations in the transcription factor OTX2 have been associated with ocular, craniofacial, and pituitary development anomalies. Here we describe a novel mutation in OTX2 associated with hypopituitarism without an ocular phenotype. |
