Genes affected

BTG2 (HGNC:1131): (BTG anti-proliferation factor 2) The protein encoded by this gene is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. This encoded protein is involved in the regulation of the G1/S transition of the cell cycle.

Dec 28, 2022

The c.94G>C (p.E32Q) alteration is located in exon 1 (coding exon 1) of the BTG2 gene. This alteration results from a G to C substitution at nucleotide position 94, causing the glutamic acid (E) at amino acid position 32 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
