Genes affected
SPP1 (HGNC:11255): (secreted phosphoprotein 1) The protein encoded by this gene is involved in the attachment of osteoclasts to the mineralized bone matrix. The encoded protein is secreted and binds hydroxyapatite with high affinity. The osteoclast vitronectin receptor is found in the cell membrane and may be involved in the binding to this protein. This protein is also a cytokine that upregulates expression of interferon-gamma and interleukin-12. Several transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2024The c.637G>A (p.A213T) alteration is located in exon 7 (coding exon 6) of the SPP1 gene. This alteration results from a G to A substitution at nucleotide position 637, causing the alanine (A) at amino acid position 213 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
