• A novel mutation p.Asn534Lys in SLCO2A1 was identified.
• A recurrent mutation c.940+1G>T in SLCO2A1 was identified.
• This finding provides clues to the phenotype–genotype relations.
Primary hypertrophic osteoarthropathy (PHO) is a rare monogenetic disease that closely mimics hypertrophic osteoarthropathy secondary to pulmonary or other pathology. The study of PHO provides an opportunity to understand both the pathogenesis of hypertrophic osteoarthropathy and the functions of the underlying genes. PHO is characterized by digital clubbing, periostosis and pachydermia. Two genes are known to be related to PHO: SLCO2A1 and HPGD. Here, we identified a recurrent heterozygous guanine-to-adenine transition at the invariant + 1 position of the donor site of intron 7 (c.940 + 1G > A) and a novel heterozygous missense mutation p.Asn534Lys (c.1602C > A) in exon 11 of SLCO2A1 in a Chinese young man with PHO. Identification of a novel genotype in PHO will provide clues to the phenotype–genotype relations and may assist not only in the clinical diagnosis of PHO but also in the interpretation of genetic information used for prenatal diagnosis and genetic counseling.
