The c.2604C>A (p.S868R) alteration is located in exon 23 (coding exon 23) of the MCF2L2 gene. This alteration results from a C to A substitution at nucleotide position 2604, causing the serine (S) at amino acid position 868 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
