Pituitary hormone deficiency
Gene: SOX3
24346842:
1 male with combined pituitary hormone deficiency (CPHD) and a maternally inherited 21-base pair deletion in SOX3 gene which resulted in loss of 7 alanine residues from the polyalanine tract. The mother was unaffected. In vitro experiments showed that the del 7A increased transactivation of the HESX1 promoter. The patient also had genetically confirmed Kabuki syndrome.
15800844:
2 male siblings with variable hypopituitarism, callosal abnormalities, anterior pituitary hypoplasia (APH), an ectopic posterior pituitary (EPP), and an absent infundibulum. They had a submicroscopic Xq27.1 duplication (685.6 kb) containing SOX3 and two transcripts of unknown function. Sox3 is expressed in the infundibulum in mice.
3 male siblings from 1 family with an absent infundibulum, severe APH, and EPP. They had a 7 alanine expansion within the polyalanine tract in SOX3. This variant led to reduced transcriptional activity, with impaired nuclear localization of the mutant protein.
21289259:
1 female with hypopituitarism and a 18-base pair deletion in SOX3 gene which resulted in loss of 6 alanine residues from the polyalanine tract. This was shown to result in a 2-fold increase in transcriptional activation in vitro, compared with wild-type SOX3.Created: 30 Oct 2025, 5:52 p.m. | Last Modified: 30 Oct 2025, 5:52 p.m.
