[Molecular identification of glucose-6-phosphate dehydrogenase (G6PD) detected in neonatal screening].

Aims: To present the strategy of identifying the molecular variants of G6PD detected in neonatal screening (NS).

Material And Methods: We present a series of incident cases of newborns positive for G6PD deficiency detected in NS. From nuclear DNA with the methodology of real-time PCR we sought molecular G6PD variants: G202A, A376G, T968C and C563T.

[RH hybrid box identification in subjects with Rh negative phenotype from Mexico's Valley].

Background: The prevalence of the RhD and RhCE gene alleles is related to the ethnic mixture. The aim of this report is to describe the predominant molecular mechanisms in RhD negative subjects residents from Mexico's valley according to the phenotype of RhCE.

Methods: Blood samples from RhD negative women and men were studied.
