Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_014668.4(GREB1):c.364G>C(p.Val122Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000204 in 1,613,906 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V122A) has been classified as Likely benign.

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.

The c.364G>C (p.V122L) alteration is located in exon 4 (coding exon 3) of the GREB1 gene. This alteration results from a G to C substitution at nucleotide position 364, causing the valine (V) at amino acid position 122 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
