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.595C>G (p.P199A) alteration is located in exon 6 (coding exon 6) of the PMF1-BGLAP gene. This alteration results from a C to G substitution at nucleotide position 595, causing the proline (P) at amino acid position 199 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
