Notes For this database we have collaborated with the Kraus lab and their databases for deficiency of cystathionine beta-synthase (CBS) and propionyl CoA carboxylase (PCC). Most data collected derive from the CBS database (Jan P. Kraus, Sarah Venezia & Mirek Janosik) and we refer to the original source for more detailed information.
Establishment of this gene variant database (LSDB) was supported by the Leiden University Medical Center (LUMC), Leiden, Nederland.
