Researchers from Saudi Arabia and Egypt describe a form of primordial dwarfism stemming from truncating mutations affecting a gene called CRIPT. The mutations were detected through the team's exome sequencing-based analysis of 16 individuals with primary dwarfism. Two of those individuals carried homozygous mutations that abbreviated CRIPT, while other affected individuals in the study had mutations affecting genes implicated in primary dwarfism in the past.
