OBJECTIVE:
To explore the clinical and genetic characteristics of a child with Pallister-Hall syndrome (PHS).
METHODS:
DNA was extracted from peripheral blood sample from the child and subjected to whole exome sequencing. Suspected variants were verified by Sanger sequencing of his family members.
RESULTS:
Genetic testing revealed that the child has harbored a heterozygous c.3320_3330delGGTACGAGCAG (p.G1107Afs×18) variant of the GLI3 gene. Neither parent was found to carry the same variant.
CONCLUSION
The c.3320_3330delGGTACGAGCAG (p.G1107Afs×18) frameshift variant of the GLI3 gene probably underlay the pathogenesis of PHS in this child. Genetic testing should be considered for patients featuring hypothalamic hamartoma and central polydactyly.
