The c.2538C>G (p.F846L) alteration is located in exon 13 (coding exon 13) of the ZFYVE28 gene. This alteration results from a C to G substitution at nucleotide position 2538, causing the phenylalanine (F) at amino acid position 846 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
