Report of an Italian family carrying a typical Indian variant of the Nilgiris tribal groups resulting from a de novo occurrence

摘要

G6PD deficiency is quite common in Italy where it is characterized by extreme molecular and biochemical heterogeneity. We report a 15-year-old Italian boy with G6PD Nilgiri (c.593G>A, p.Arg198His), a typical Indian variant of the Nilgiris tribal groups. Further, this variant was biochemically characterized, and the molecular screening of the family highlighted a de novo mutational event. To date, this family is the first Caucasian family carrying the G6PD Nilgiri variant.
