Common and recurrent HPGD mutations in Caucasian individuals with primary hypertrophic osteoarthropathy

Abstract

Biallelic HPGD mutations are found in the majority of patients with typical PHO, and sequencing of the HPGD gene is a highly specific first-line investigation for patients presenting in this way, particularly during childhood. The c.175_176delCT frameshift mutation appears to be recurrent and to be the commonest HPGD mutation in Caucasian families.
