The study identifies a non-consanguineous multigenerational family of the Lua ethnic group in Northern Thailand with three members affected with hypoplastic-hypocalcified amelogenesis imperfecta, cone-rod dystrophy, and harboring a novel homozygous missense variant, c.1475G>A p.(Gly492Asp), in CNNM4, indicating Jalili syndrome. We report features including advanced dental age, crossbite, developmental delay, expanding genotypic and phenotypic spectra of Jalili syndrome, and perform the prenatal genetic testing that helps avoid unnecessary pregnancy termination.
