Detailed examinations of three affected calves revealed proximal limb shortening, epiphyseal calcific deposits, and other pathological signs consistent with human rhizomelic chondrodysplasia punctata, a rare peroxisomal disorder caused by recessive variants in one of five genes (AGPS, FAR1, GNPAT, PEX5, and PEX7). This evidence concerns the gene GNPAT and rhizomelic chondrodysplasia punctata.
