Comment

Parvari et al. (2001, 2005) identified PREPL as one of the genes deleted in the homozygous 2p21 deletion syndrome. Jaeken et al. (2006) studied 11 patients with the hypotonia-cystinuria syndrome, also known as the 2p21 deletion syndrome. They found microdeletion of part of the SLC3A1 and PREPL genes on 2p21. Since loss-of-function mutations in SLC3A1 were known to cause isolated cystinuria type I , and since the expression of the flanking genes, C2orf34 and PPM1B, was normal, the extended phenotype could be attributed to deletion of PREPL.
