Homocystinuria due to cystathionine b-synthase (CBS) deficiency is frequently caused by missense mutations. In this article, we report four novel missense mutations in the CBS gene: 172C®T (R58W) linked in cis with A114V; 376A®G (M126V); 904G®A (E302K); and 1006C®T (R336C). The CBS activity of the c
RT-PCR and direct sequence analyses were used to define mutations in the cystathionine b -synthase (CBS) gene in two unrelated male patients with vitamin B6 nonresponsive homocystinuria. Both patients were compound heterozygotes for CBS alleles containing point mutations. One patient had a maternall
