AGK and cataract: We note that genetic mutations in several other lipid metabolism enzymes are known to elicit cataracts in humans, including lanosterol synthase (LSS, MIM no. 600909; autosomal recessive congenital cataract, CTRCT44, MIM no. 616509) (Zhao et al. 2015; Zhao et al. 2021) and acylglycerol kinase (AGK, MIM no. 610345; Sengers syndrome, MIM no. 212350; and a non-syndromic form of autosomal recessive congenital cataract, CTRCT38, MIM no. 614691) (Aldahmesh et al. 2012; Mayr et al. 2012).
