The c.943C>T (p.R315W) alteration is located in exon 7 (coding exon 7) of the BCO2 gene. This alteration results from a C to T substitution at nucleotide position 943, causing the arginine (R) at amino acid position 315 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
