Jul 19, 2023

The c.1153C>G (p.Q385E) alteration is located in exon 8 (coding exon 8) of the BCO2 gene. This alteration results from a C to G substitution at nucleotide position 1153, causing the glutamine (Q) at amino acid position 385 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
