Gene Mutation Analysis and Prenatal Diagnosis of the Ornithine Transcarbamylase (OTC) Gene in Two Families with Ornithine Transcarbamylase Deficiency.

ABSTRACT: BACKGROUND The 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 AND METHODS The 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. RESULTS The probands were both confirmed to have OTCD. The proband in Family 1 was a male carry
