The c.7G>A (p.E3K) alteration is located in exon 1 (coding exon 1) of the CD3EAP gene. This alteration results from a G to A substitution at nucleotide position 7, causing the glutamic acid (E) at amino acid position 3 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
