Abstract:
OBJECTIVETo determine the molecular basis of late onset ornithine transcarbamylase (OTC) deficiency in a Chinese family of Han nationality and the exon sequences of OTC gene of this patient.
METHODSPolymerase chain reaction-single strand conformation polymorphism and direct sequencing were used to identify the mutation type.
RESULTSA missense mutation E122G in the conserved residue of exon 4 was identified which is unreported before.
CONCLUSIONThe E122G mutation in human OTC gene may cause late onset OTC deficiency.
