Rhizomelic chondrodysplasia punctata is a rare, often fatal disease that shares many clinical dysmorphologic features with the rare often non-lethal chondrodysplasia punctata due to maternal autoimmune disease. Characteristic findings of both conditions include mid-face hypoplasia, stippled epiphyses of the vertebrae and long bones, and growth failure. A growing association with anti-ribonucleoprotein antibodies is emerging amongst patients with chondrodysplasia punctata due to maternal autoimmune disease and also neonatal lupus that have potential important screening implications. We present a unique case of chondrodysplasia punctata with neonatal lupus in the setting of positive anti-RNP antibodies and negative anti-Ro/SSA and -La/SSB antibodies born to a mother with mixed connective tissue disease and Raynaud's syndrome. © 2020 Wiley Periodicals LLC.
