Genes affected

HMMR (HGNC:5012): (hyaluronan mediated motility receptor) The protein encoded by this gene is involved in cell motility. It is expressed in breast tissue and together with other proteins, it forms a complex with BRCA1 and BRCA2, thus is potentially associated with higher risk of breast cancer. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Dec 2008]

The c.620A>G (p.Q207R) alteration is located in exon 7 (coding exon 7) of the HMMR gene. This alteration results from a A to G substitution at nucleotide position 620, causing the glutamine (Q) at amino acid position 207 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
