[Analysis of SATB2 gene mutation in a child with Glass syndrome].

ABSTRACT

OBJECTIVE: To analyze the clinical characteristics and genetic basis of a child affected with Glass syndrome. METHODS: Clinical manifestations and auxiliary examination results of the child were analyzed. Potential mutation was detected with next generation sequencing and validated by Sanger sequencing. RESULTS: The child has featured growth and mental retardation, delayed speech, cleft palate, crowding of teeth, and downslanting palpebral fissures. DNA sequencing revealed a de novo heterozygous missense mutation c.1166G>A (p.R389H) in exon 8 of the SATB2 gene in the child. CONCLUSION: The heterozygous mutation c.1166G>A (p.R389H) of the SATB2 gene probably account for the Glass syndrome in the patient.
