In our study we investigated the contribution of heterozygosity for common variations considered either potentially pathogenic or susceptibility alleles for cholesterol cholelithiasis in adults (c.523A>G (p.Thr175Ala) and c.1954A>G (p.Arg652Gly) in ABCB4, c.1331T>C (p.Val444Ala) in ABCB11 and c.55 G>C (p.Asp19His) in ABCG8) to the aetiology of paediatric idiopathic gallstone disease.
Studies have identified single nucleotide polymorphisms (SNP) D19H and T400K in the cholesterol transporter gene ATP-binding cassette, subfamily G, member 8 (ABCG8) in patients with cholesterol gallstones.
Mutational analysis of ABCB4, screening for copy number variations by multiplex ligation-dependent probe amplification, genotyping for low expression allele c.1331T>C of ABCB11 and genotyping for variation c.55G>C in ABCG8 previously associated with cholesterol gallstones in adults was performed in 35 pediatric subjects with idiopathic gallstones who fulfilled the clinical criteria for low phospholipid-associated cholelithiasis syndrome (LPAC, OMIM #600803) and in 5 young females with suspected LPAC and their families (5 probands, 15 additional family members).
