New technique determines which patients with homocystinuria are most likely to respond to vitamin B6 treatment based on their genotypes

A new technique, surrogate organism genetics, has been used to “swap” yeast genes with human genes sequenced from patients with homocystinuria to determine the gene variants likely to respond to vitamin B6 treatment.

Common gene variants appear to increase risk of vitamin D deficiency

Scientists have identified four common gene variants that are associated with blood levels of vitamin D and with an increased risk of vitamin D deficiency.
