Abstract:
OBJECTIVE:To explore the correlation between the genotypes and metabolic markers and microstructure of bones in children with Gitelman syndrome (GS).
METHODS:For 15 children with GS and 10 healthy individuals, baseline data and bone metabolic markers including parathyroid hormone, alkaline phosphatase, osteocalcin, N-terminal propeptide of type I procollagen, beta isomer of the C-terminal telopeptide of type I collagen and 25-hydroxyvitamin D, high-resolution peripheral quantitative computed tomography indicators (volumetric bone mineral density, bone microstructure indicators) were collected. Genetic testing was carried out to determine their genotypes.
RESULTS:The volumetric bone mineral density, bone geometry and bone microstructure parameters of the GS group were better than those of the healthy controls (P<0.05). Variants of the SLC12A3 gene were identified in 9 of the 15 patients but none of the 10 healthy controls.
CONCLUSION:The phenotype of GS children is influenced by the interaction of genetic variants, though the phenotype associated with high frequency mutations showed no specificity. There is also a correlation between their genotype and the bone microstructure.
