DAL BORGO A, Patricia; ROSARIO, Silva C  y  CAVIERES A, Mirta. Two new glucose 6 phospho-dehydrogenase mutations, G6PD Santiago and G6PD Calvo Mackenna. Rev. chil. pediatr. [online]. 2000, vol.71, n.5, pp. 419-422. ISSN 0370-4106.  doi: 10.4067/S0370-41062000000500007.

Two undescribed mutations that produce G6PD deficiency in Chilean boys are documented. Both occurred in patients with hereditary non-spherocytic haemolytic anaemia. G6PD Santiago was due to an Arg-Pro change at amino acid 198 because of a C transition at nucleotide 593. G6PD Calvo Mackenna was due to a A-G transition at nucleotide 1138 resulting in a substitution of valine for isoleucine at amino acid 380. The studies were carried out in the Scripps Research Institute in La Jolla, California, USA by courtesy of Dr. Ernest Beutler
