The c.137A>G (p.K46R) alteration is located in exon 2 (coding exon 1) of the ZBTB9 gene. This alteration results from a A to G substitution at nucleotide position 137, causing the lysine (K) at amino acid position 46 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
