In the same experimental group at different ages: the relative expression levels of VDR mRNA in the thoracic vertebra tissue of the CHF and BPs groups at the age of 30 days were higher than those at the age of 60 days, and the CHF-M group and the BPs-H group at the age of 30 days were significantly higher than those at the age of 60 days (p < 0.05). The gene discussed is VDR; the disease is Bartsocas-Papas syndrome 1.
