Genes affected

GREB1 (HGNC:24885): (growth regulating estrogen receptor binding 1) This gene is an estrogen-responsive gene that is an early response gene in the estrogen receptor-regulated pathway. It is thought to play an important role in hormone-responsive tissues and cancer. Three alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

Collection Method: clinical testing

The c.80G>A (p.R27Q) alteration is located in exon 2 (coding exon 1) of the GREB1 gene. This alteration results from a G to A substitution at nucleotide position 80, causing the arginine (R) at amino acid position 27 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
