The c.1677C>G (p.D559E) alteration is located in exon 13 (coding exon 12) of the CALCOCO1 gene. This alteration results from a C to G substitution at nucleotide position 1677, causing the aspartic acid (D) at amino acid position 559 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
