75 All of the mutations were missense mutations and were found in the region of the protein encoded by exons 28-32: 4139A!G (N1380S) and 4142G!A (G1381E) in exon 28, 4541G!A (R1514H) in exon 30, 4615G!A (E1539K) in exon 31 and 4951G!A (G1651S) in exon 32. Login to comment
88 Four of the mutations (N1380S, G1381E, R1514H, E1539K) were situated in the first highly conserved ATP binding domain of the protein (Fig. 4). Login to comment

28 Patients 2 and 3 had compound heterozygosity of missense /splice-site mutations [(p.Arg986Trp)+(c.5940-1G>C), (p.Asn1380Ser)+(c.5128+ 3A>G), respectively]. Login to comment

38 Two recurrent mutations (p.Asn1380Ser and p.Gly1651Ser) have been reported previously in LI2.6 These mutations were not found in 200 normal, unrelated Japanese alleles. Login to comment

50 The second most common reported ABCA12 mutation is a missense mutation p.Asn1380Ser in Walker A motif of the first ATP-binding cassette, which is essential for the transporter function of ABCA12 [Lefe`vre et al., 2003]. Login to comment
51 This missense mutation p.Asn1380Ser has been identified in five LI families from Africa (three families from Morocco and two families from Algeria) [Lefe`vre et al., 2003]. Login to comment
52 Haplotype analysis confirmed that p.Asn1380Ser is a founder mutation in the patients from Morocco/Algeria region [Lefe`vre et al., 2003]. Login to comment

10 Oligonucleotide primers and polymerase chain reaction conditions used for amplification of all ABCA12 exons and exon-intron borders were originally derived from the report by Lef evre et al.3 Two heterozygous ABCA12 mutations were identified in the patient: the novel missense mutation c.6431T>C (p.Phe2144Ser) in exon 44, which was not detected in the 100 control alleles (50 individuals; data not shown), and the known missense mutation c.4139A>G (p.Asn1380Ser) in exon 28 (Fig. 1c).

11 p.Asn1380Ser was previously reported as an LI-causative mutation.3 p.Asn1380Ser was present in the mother and p.Phe2144Ser was demonstrated as paternal (data not shown). Login to comment
14 The homozygous mutation p.Asn1380Ser and the compound heterozygous mutations p.Asn1380Ser and p.Gly1651Ser were previously reported to underlie typical LI phenotypes.3 In this regard, we hypothesized that the difference between p.Asn1380Ser/p.Gly1651Ser and p.Phe2144Ser may determine whether the phenotype is LI or CIE.
