Primary autosomal recessive hypertrophic osteoarthropathy (PHOAR) type 1 is caused by the failure of the HPGD gene product to break down prostaglandins. We report the case of a two-year-old male patient diagnosed with PHOAR1 due to a previously unreported homozygous intragenic deletion. Upon retrospective review of the patient's history, his clinical course proved to be typical of this syndrome, although it had been unrecognized. This case report presents an opportunity to review the natural history, clinical signs, diagnosis, and treatment of PHOAR1, with the aim of raising awareness of this rare entity.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
