The c.2398C>T (p.R800W) alteration is located in exon 1 (coding exon 1) of the AP5B1 gene. This alteration results from a C to T substitution at nucleotide position 2398, causing the arginine (R) at amino acid position 800 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
