I am een Dutch women 64 years old and in 2011 I heared the diagnosis Cystathioninuria (gamma-cystathionase deficiency)
I want to keep in touch with more patients because in Holland there are no other patients. Please write me !
I have also problems with vitamine B12 and Hyperhomocysteinemia
My english is not so well, but I'll do my best ! If necessary I can use Google translante
