Ively. Filled symbols denote affected status. The proband is indicated by an arrow. 4 chosen microsatellite markers (D11S904, D11S914, D11S1751 and D11S935) flanking PAX6 gene listed in descending order from the centromeric end. PAX6 gene is positioned involving D11S914 and D11S1751 on 11q13. The disease-related haplotype is arisen from non-sister chromatids with the proband’s father (I51) by crossing-over. The proband (II51) transmitted it to his affected son(III51).underlying mechanism remains unclear. The present de novo duplication mutation may well outcome from an unequal crossing-over among non-sister chromatids during spermatogenesis, when the breakpoints and junction occurred precisely at the mutation site.Table 1 | PCR primers applied for amplification of PAX6 geneExon 1,two three,4 5 , 5a 6,7 eight,9 ten , 11 12 , 13 Primer Name PAX6-1MF PAX6-2MR PAX6-3MF PAX6-4MR PAX6-5MF PAX6-5aMR PAX6-6MF PAX6-7MR PAX6-8MF PAX6-9MR PAX6-10MF PAX6-11MR PAX6-12MF PAX6-13MRM13 forward primer or reverse primer 1 specific sequence 59-39 TGTAAAACGACGGCCAGTCTCATTTCCCGCTCTGGTTC CAGGAAACAGCTATGACCAAGCGAGAAGAAAGAAGCGG TGTAAAACGACGGCCAGTTCAGAGAGCCCATGGACGTAT CAGGAAACAGCTATGACCGAAGTCCCAGAAAGACCAGA TGTAAAACGACGGCCAGTCTCTTCTTCCTCTTCACTCTG CAGGAAACAGCTATGACCGGGAAGTGGACAGAAAACC TGTAAAACGACGGCCAGTGGTTTTCTGTCCACTTCCC CAGGAAACAGCTATGACCAGCATGGAAGCCCTGAGAGGA TGTAAAACGACGGCCAGTGGGAATGTTTTGGTGAGGCT CAGGAAACAGCTATGACCGTACTCTGTACAAGCACCTC TGTAAAACGACGGCCAGTGTAGACACAGTGCTAACCTG CAGGAAACAGCTATGACCTTATGCAGGCCACCACCAGC TGTAAAACGACGGCCAGTTAATGATCAGACTTGTTGGCAG CAGGAAACAGCTATGACCGAACTGAAGCGGCTCTAACAProduct size(bp) 472 625 1117 1209 960 431DNA sequencing primers: M13 forward primer (TGTAAAACGACGGCCAGT) and M13 reverse primer (CAGGAAACAGCTATGACC; PCR conditions: 94uC/59; 94uC/300,58uC/450,72uC/1 , 29,ten cycles; 94uC/300,61uC/450,72uC/1 , 29,25 cycles; 72uC/59; 4uC/`.109781-47-7 Chemscene SCIENTIFIC REPORTS | four : 4836 | DOI: 10.Formula of 1699751-03-5 1038/srepnature/scientificreports1.PMID:33615956 Kokotas, H.
