The c.2419G>A (p.E807K) alteration is located in exon 3 (coding exon 1) of the ZBTB21 gene. This alteration results from a G to A substitution at nucleotide position 2419, causing the glutamic acid (E) at amino acid position 807 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
