59 The majority of patients (42/71, 59.1%) were compound heterozygotes for two missense mutations or one nonsense and one missense mutations, and 12 patients (16.9%) were simple heterozygotes. Only three patients were found to be homozygous for ABCR variants (324-327insT, V1433I, and A1598D). Login to comment

123 In these cases, the total inactivation of the splice site is unlikely, although these changes could alter the splicing of corresponding exon, creating cryptic sites, thus producing a longer protein.21 In two patients diagnosed as having arCRD and arRP phenotypes respectively, we identified the missense p.Val1433Ile mutation, located in the second transmembrane domain.

8 A lack of familial segregation was observed in 4 of 6 codon changes (Arg943Gln, Val1433Ile, Pro1948Leu, and Ser2255Ile). Login to comment
40 The heterozygous codon changes observed were Pro940Arg, Arg943Gln (2 families), Pro1948Leu (2 families), Leu1970Phe, Val1433Ile, and Ser2255Ile. Login to comment
42 Conversely, the Pro940Arg, Val1433Ile, and Leu1970Phe changes were not found in the control group. Login to comment
43 No cosegregation of the base substitution with the disease was observed in the families harboring either Arg943Gln, Val1433Ile, Pro1948Leu, or Ser2255Ile changes. Login to comment
63 First, a lack of segregation was observed, for the Arg943Gln, Val1433Ile, Pro1948Leu, and Ser2255Ile changes. Login to comment
68 It is worth noting that Val1433Ile, not observed in controls, was excluded only using segregation analysis. Login to comment
