Heterozygous de novo missense pathogenic variants in PTDSS1 that result in gain-of-function of phosphatidylserine synthase 1 are associated with Lenz-Majewski hyperostotic dwarfism (LMHD). We identified the novel heterozygous de novo variant p.(Leu137Phe) in PTDSS1 in a child with mild-to-moderate developmental delay. Skeletal survey revealed no evidence of LMHD in this patient. Functional assessment of the p.Leu137Phe variant was performed by overexpressing the mutant protein into HEK293 cells. Following C14 -serine labeling and TL
