The c.1029T>G (p.I343M) alteration is located in exon 2 (coding exon 2) of the EGR4 gene. This alteration results from a T to G substitution at nucleotide position 1029, causing the isoleucine (I) at amino acid position 343 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
