Genes affected

BGLAP (HGNC:1043): (bone gamma-carboxyglutamate protein) This gene encodes a highly abundant bone protein secreted by osteoblasts that regulates bone remodeling and energy metabolism. The encoded protein contains a Gla (gamma carboxyglutamate) domain, which functions in binding to calcium and hydroxyapatite, the mineral component of bone. Serum osteocalcin levels may be negatively correlated with metabolic syndrome. Read-through transcription exists between this gene and the neighboring upstream gene, PMF1 (polyamine-modulated factor 1), but the encoded protein only shows sequence identity with the upstream gene product.

The c.79G>A (p.G27S) alteration is located in exon 2 (coding exon 2) of the BGLAP gene. This alteration results from a G to A substitution at nucleotide position 79, causing the glycine (G) at amino acid position 27 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
