When N314D is present on the same GALT allele (in cis) as the c.-119_116delGTCA promoter variant (Duarte-2 variant), the result is an impaired regulatory domain of the GALT enzyme and approximately 50% of normal galactose-1-phosphate uridyltransferase (GALT) activity (Bosch et al., 2005). Newborns who are compound heterozygotes for the Duarte-2 variant (D variant) and a variant associated with classic galactosemia (G variant) are considered to have Duarte-2 variant galactosemia or D/G galactosemia which may be identified by newborn screening programs and is associated with approximately 50% of control galactosyltransferase activity, on average (Berry, 2014).
