8 In the C-terminal part of ABCA1, known to interact with other proteins, two novel sequence variations (F2163S and V2244I) have been found in one phenotype related to cardiovascular disease, but none in the aforementioned cohorts. Login to comment

202 Several sequence variations were identified, with two of them located within exon 49 (F2163S) and exon 50 (V2244I) near the COOH-terminus of ABCA1. Login to comment
203 Analysis of the rest of the family focusing on the identified polymorphisms revealed that the mother is heterozygous for F2163S and the father is heterozygous for V2244I. Login to comment
230 However, the sequence variations found in patient E with G6PD deficiency (F2163S, V2244I) are located in exons 49 and 50, respectively, and these mutations may account for the low-HDL cholesterol. Login to comment
232 The coincidence of polymorphisms within exon 50 (V2244I) of the carboxyterminus of the ABCA1 gene and clinical correlates of succinate dehydrogenase deficiency and hypertrophic cardiomyophathy and skeletal muscle myopathy in the father (pedigree C, Fig. 1) without mutations in the G6PD gene indicates that the mutation in exon 50 of ABCA1 is causally related to dysfunctions of succinate dehydrogenase and/or G6PD, perhaps by interfering with correct protein-protein interactions and failure of shuttling between ABCA1 and the inner mitochondrial membrane.
