ABSTRACT
BACKGROUND:
Pituitary stalk interruption syndrome (PSIS) and holoprosencephaly (HPE) are congenital midline defects. Rare mutations in the sonic hedgehog (SHH) signaling gene CDON have recently been reported in patients with HPE.OBJECTIVE:
To report a unique case of PSIS with a maternally inherited nonsense mutation in the SHH signaling protein CDON.METHOD:
We performed exome sequencing on a case of PSIS. Control databases (1000 Genomes, dbSNP, Exome Variant Server, ExAC Browser) and an ancestry-matched control panel were screened upon identification of CDON mutation.RESULTS:
We identified a novel heterozygous nonsense mutation (c.2764T>C, Glu922Ter) in a case of PSIS without HPE who presented with neonatal hypoglycemia and cholestasis associated with GH, TSH, and ACTH deficiencies. This mutation was absent in all control databases and from 400 healthy ancestry-matched control subjects. The mutation was inherited from the patient's mother, who was operated on in childhood for strabismus. The absence of this variant in control samples suggests that it is likely to be responsible for the phenotype.CONCLUSION:
We report for the first time a mutation in the CDON gene associated with PSIS.
