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]

May 14, 2024

The c.610G>A (p.E204K) alteration is located in exon 7 (coding exon 7) of the HMMR gene. This alteration results from a G to A substitution at nucleotide position 610, causing the glutamic acid (E) at amino acid position 204 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
