Abstract | BACKGROUND AND STUDY AIMS: PATIENTS AND METHODS: This observational case-control study was conducted on 13 children with suspected PFIC2 and 13 healthy subjects as controls. Genotyping of the ABCB11 gene was performed via DNA extraction followed by PCR amplification, purification, and then sequencing analysis of exons 14, 15, and 24 of the ABCB11 gene. RESULTS: The study detected two single nucleotide variations, c.1638+ 32T > C (rs2241340) in exon 14 and c.3084A > G (p.Ala1028 = ) (rs497692) in exon 24 of the ABCB11 gene. No variations were identified in exon 15. CONCLUSION: The study revealed two benign variants involving exons 14 and 24 of the ABCB11 gene. Exons 14, 15, and 24 are not hot spots for common mutations in Egyptian PFIC2 patients. Further study of other exons of the ABCB11 gene is necessary to confirm the diagnosis of PFIC2.
