Genes affected

CCDC170 (HGNC:21177): (coiled-coil domain containing 170) The function of this gene and its encoded protein is not known. Several genome-wide association studies have implicated the region around this gene to be involved in breast cancer and bone mineral density, but no link to this specific gene has been found.

The c.818A>G (p.E273G) alteration is located in exon 6 (coding exon 6) of the CCDC170 gene. This alteration results from a A to G substitution at nucleotide position 818, causing the glutamic acid (E) at amino acid position 273 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
