Lenz-Majewski syndrome (LMS), also known as Lenz-Majewski hyperostotic dwarfism, is an extremely rare syndrome characterized by osteosclerosis, intellectual disability, characteristic facies, and distinct craniofacial, dental, cutaneous and distal-limb anomalies. Mutations in the PTDSS1 gene coding one of the phosphatidylserine (PS) synthase enzymes, PSS1, have been described as causative in LMS patients. Such mutations render PSS1 insensitive to feedback inhibition by PS levels.
