The c.5798G>C (p.R1933P) alteration is located in exon 1 (coding exon 1) of the C2orf16 gene. This alteration results from a G to C substitution at nucleotide position 5798, causing the arginine (R) at amino acid position 1933 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
