The c.1625G>A (p.R542Q) alteration is located in exon 5 (coding exon 4) of the ZBTB46 gene. This alteration results from a G to A substitution at nucleotide position 1625, causing the arginine (R) at amino acid position 542 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
