We report on a consanguineous Lebanese family in which two sibs had pre- and post-natal growth retardation, developmental delay, large anterior fontanel, prominent forehead, low-set ears, depressed nasal bridge, short nose, anteverted nares, increased nasal width, prominent abdomen, and short limbs. Radiographs disclosed the presence of wormian bones, platyspondyly, decreased interpedicular distance at the lumbar vertebrae, square iliac bones, horizontal acetabula, trident acetabula, hypoplastic ischia, partial agenesis of the sacrum, ribs with cupped ends, short long bones with abnormal modeling, slight widening of the distal femoral metaphyses, and delayed epiphyseal ossification. Both sibs had a severe cardiomegaly and died at around 24 months from a heart failure. Differential diagnosis suggests that this is a second family presenting a newly described early lethal chondrodysplasia first reported by [Megarbane et al. (2008); Am J Med Genet Part A 146A:2916-2919]. (c) 2014 Wiley Periodicals, Inc.
