“…OTCD belongs to the X-linked recessive genetic disorders; therefore, almost all hemizygous males develop this disease. Approximately 20% of female carriers present some neurocognitive disorders due to unfavorable random X-inactivation; however, the symptoms are substantially milder than those of male patients [4].…”

BackgroundThe aim of this study was to perform gene detection in 2 clinical cases of highly suspected ornithine transcarbamylase deficiency (OTCD) pediatric patients by first-generation sequencing technology in order to confirm the pathogenic genetic factors of their families and allow the families to undergo genetic counselling and prenatal diagnosis.Material/MethodsThe peripheral DNA samples of 2 children with highly suspected OTCD (the probands) and their parents were collected. DNA fragments corresponding to exons 1–10 of the OTC gene from the samples were amplified using polymerase chain reaction (PCR), and then subjected to Sanger sequencing to confirm the pathogenic mutation sites.ResultsThe probands were both confirmed to have OTCD. The proband in Family 1 was a male carrying a c.867+1G>C mutation at a splice site within the OTC gene. The gene detection results of amniotic fluid cells at 16 weeks of pregnancy showed that the fetus was a male who also carried the c.867+1G>C mutation. The proband in Family 2 was a male carrying a c.782T>C(p. I261T) mutation in the OTC gene. The gene detection results of amniotic fluid cells at 18 weeks showed that the fetus was a male without pathogenic mutations in the OTC gene. The gene detection results of peripheral blood from the fetus after birth were consistent with those obtained from amniotic fluid cells.ConclusionsPediatric children who are clinically suspected of OTCD can receive a definitive diagnosis through OTC gene detection.
