The c.2010C>A (p.S670R) alteration is located in exon 8 (coding exon 8) of the ZFYVE28 gene. This alteration results from a C to A substitution at nucleotide position 2010, causing the serine (S) at amino acid position 670 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
