      CaseGenotypingMethod: DNA was isolated from peripheral blood samples and from liver samples collected at autopsy. A genome-wide screen with 343 different markers was carried out and linkage analysis performed using homozygosity mapping. Both SLC6A18 and SLC6A19 were investigated for possible pathogenicity, with SLC6A19's pattern of expression supporting it as a primary candidate. Intronic primers were used to bidirectionally sequence each exon and flanking intronic regions, locating a homozygous missense mutation that perfectly segregated with the phenotype.
