- Description:
- Autosomal dominant polycystic liver disease (ADPLD) and autosomal dominant polycystic kidney disease (ADPKD) is caused by mutations in PRKCSH, SEC63, and LRP5, PKD1, and PKD2. Liver cyst development in these disorders is explained by somatic loss-of-heterozygosity (LOH) of the wild type allele in the developing cyst. We analyzed 24 liver cyst samples from 23 patients using high resolution microarray (homozygosity of autosomes (>3.0Mb) large CNVs (>1.0Mb)). We found frequent LOH in PRKCSH (22/29), and PKD1/PKD2 (2/3). In the total cohort, 12/23 patients harbored abnormalities outside of familiar areas. In individual ADPLD cases, we identified germline events: a 2q13 complex rearrangement resulting in BUB1 haploinsufficiency, a 47XXX karyotype, and LOH on chromosome 3p.
