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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.296G>A (p.R99H) alteration is located in exon 5 (coding exon 5) of the HMMR gene. This alteration results from a G to A substitution at nucleotide position 296, causing the arginine (R) at amino acid position 99 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
