After confirming lack of a founder haplotype in three families, we analyzed PRPSAP1 and PRPSAP2 as candidate genes for hyperuricemia on chr 17 where COL1A1 is located, but found no mutation.
In this study, the levels of Wnt3a and differentiation-related factors, including Runx2, Sp7, Ibsp, Bglap, Dmp1, and Col1a1, were all evidently decreased in HUC rats, while the presence of ALLO increased the levels of above factors.
