The c.1597G>A (p.E533K) alteration is located in exon 9 (coding exon 8) of the TBRG4 gene. This alteration results from a G to A substitution at nucleotide position 1597, causing the glutamic acid (E) at amino acid position 533 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
