The c.268C>G (p.Q90E) alteration is located in exon 4 (coding exon 4) of the ZG16B gene. This alteration results from a C to G substitution at nucleotide position 268, causing the glutamine (Q) at amino acid position 90 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
