We provide the proof of principle that exome sequencing of only two affected siblings born to first-cousin parents is capable of directly identifying a single candidate gene for an autosomal recessive disorder. This strategy, which we call EX-HOM (EXome HOMozygosity), combines in a single step the capacity of exome sequencing to identify all the coding variants present in a genome with the property of homozygosity mapping to limit the search for candidate genes to specific chromosomal regions.
