Genes affected

BTG4 (HGNC:13862): (BTG anti-proliferation factor 4) 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 can induce G1 arrest in the cell cycle. [provided by RefSeq, Jul 2008]

The c.557G>A (p.R186H) alteration is located in exon 5 (coding exon 4) of the BTG4 gene. This alteration results from a G to A substitution at nucleotide position 557, causing the arginine (R) at amino acid position 186 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
