13 Two patients were homozygous for mutations in the coding region of the ABCA1 gene, resulting in an amino acid substitution (p.A1046D) and a truncated protein (p.I74YFsX76).

210 The proband of family 1 was homozygous for a missense mutation (p.A1046D) previously reported by Wang et al. [31] in a kindred with HDL deficiency, which included three compound heterozygotes (whose second mutant allele was a nucleotide insertion in exon 34 - c.4630 ins A - causing a frameshift) and two heterozygotes for this mutation.

211 Previous in vitro experiments have shown that the p.A1046D mutation, which occurs in the intracellular domain between the first Walker A and B motifs, severely impairs cholesterol efflux from transfected cells, even if it does not abolish the localization of ABCA1 in the plasma membrane, where it retains a residual capacity to bind Apo A-I [32].
