The c.1903C>G (p.L635V) alteration is located in exon 8 (coding exon 8) of the ZFYVE28 gene. This alteration results from a C to G substitution at nucleotide position 1903, causing the leucine (L) at amino acid position 635 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
