The c.268C>T (p.R90W) alteration is located in exon 4 (coding exon 3) of the ADCK1 gene. This alteration results from a C to T substitution at nucleotide position 268, causing the arginine (R) at amino acid position 90 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
