Among these, mutations in SLC20A2 account for approximately 45% of all autosomal dominant and de novo reported familial cases from diverse ethnicities.3 However, a large proportion of autosomal recessive PFBC remain undiagnosed.4 Recently, biallelic mutations in MYORG (OMIM: 618255) have been implicated in the pathogenesis of autosomal recessive PFBC in families of Chinese5 and French6 ethnicity. The gene discussed is SLC20A2; the disease is bilateral striopallidodentate calcinosis.
