It has been associated with hyperoxaluria with NL and NC with variants in PEX1 (Alhazmi, 2018), likely with variants in PEX5 (van Woerden et al., 2006), and possibly with variants in PEX3, PEX6, PEX 10, PEX 12, PEX13, PEX14, PEX16, PEX19, and PEX26 (Braverman et al., 2016; Alhazmi, 2018). This evidence concerns the gene PEX5 and Hyperoxaluria.
