The Spectrum of Mutations of Homocystinuria in the MENA Region
(
MDPI
, 2020 , Article Review)
Homocystinuria is an inborn error of metabolism due to the deficiency in cystathionine beta-synthase (CBS) enzyme activity. It leads to the elevation of both homocysteine and methionine levels in the blood and urine. ...
The Current Status of Cytomegalovirus (CMV) Prevalence in the MENA region: a systematic review
