The c.898C>G (p.Q300E) alteration is located in exon 1 (coding exon 1) of the CTAGE15 gene. This alteration results from a C to G substitution at nucleotide position 898, causing the glutamine (Q) at amino acid position 300 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
