Mutations in the CYP27B1 gene cause vitamin D dependent rickets in pugs
Abstract Rickets is a disorder of bone development and can be the result of either dietary or genetic causes. Here, related pugs from 2 litters were included. Three pugs had clinical signs including, lameness, bone deformities, and dyspnea. One other pug was found dead. Radiographs of 2 affected pug...

description | Abstract Rickets is a disorder of bone development and can be the result of either dietary or genetic causes. Here, related pugs from 2 litters were included. Three pugs had clinical signs including, lameness, bone deformities, and dyspnea. One other pug was found dead. Radiographs of 2 affected pugs, 5 and 6 months old, showed generalized widening, and irregular margination of the physes of both the appendicular and the axial skeleton with generalized decrease in bone opacity and bulbous swelling of the costochondral junctions. Two pugs had low serum calcium and 1,25 (OH)2D3 concentrations. Test results further indicated secondary hyperparathyroidism with adequate concentrations of 25‐hydroxyvitamin D. Necropsy revealed tongue‐like projections of cartilage extending into the metaphysis consistent with rickets, loss of metaphyseal mineralization and lung pathology. Vitamin D‐dependent rickets was diagnosed. A truncating mutation in the 1α‐hydroxylase gene (CYP27B1) was identified by genome sequence analysis of the pugs with VDDR type 1A. Vitamin D‐dependent rickets type 1A can occur in young pugs, and if left untreated is a life‐threatening condition. Early medical intervention can reverse clinical signs and should be instituted as soon as possible. |
