Analysis of the c.187 C> T mutation in ATP6V0A2 by PCR-ARMS

Abstract

Congenital disorders of glycosylation (CDG) are rare hereditary metabolic diseases (EPOF) that occur as a result of mutations in the genes coding for proteins involved direct or indirectly in this process. Autosomal Recessive Cutis Laxa disease type II-A (ARCL2A) is a type of CDG (ATP6V0A2-CDG) caused by mutations in ATP6V0A2, which codes for the a2 subunit of the v0 domain of a vacuolar ATPase that has the function of transporting H⁺ through cell membranes, regulating pH in cells compartments, including Golgi acidification. In 2014, our research group reported the first two cases of ATP6V0A2-CDG in Mexico. In this work, a methodology was established to identify carriers of the c.187 C> T mutation in ATP6V0A2 by PCR-ARMS.
