Abstract
Abstract Mutations in the PEX7 gene encoding a peroxisome targeting signal 2 (PTS2) were identified in two patients with rhizomelic chondrodysplasia punctata (RCDP). A 7-year-old girl, the first Japanese individual to be diagnosed biochemically as a case of RCDP, had a novel nonsense mutation, R232ter, in the PEX7 gene, which had been inherited from her consanguineous parents. Another patient, a Chilean boy with RCDP, had compound heterozygous mutations of PEX7, L292ter and A218V, both of which have been documented. R232ter, which deletes all of the last two WP40 repeats in the PEX7 gene, is sufficient to inactivate functions of the PEX7 gene. [ABSTRACT FROM AUTHOR]
