Genes affected

BMP6 (HGNC:1073): (bone morphogenetic protein 6) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein regulates a wide range of biological processes including iron homeostasis, fat and bone development, and ovulation. Differential expression of this gene may be associated with progression of breast and prostate cancer. Mutations in this gene may be associated with iron overload in human patients.

Collection Method: clinical testing

The c.289C>T (p.H97Y) alteration is located in exon 1 (coding exon 1) of the BMP6 gene. This alteration results from a C to T substitution at nucleotide position 289, causing the histidine (H) at amino acid position 97 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
