The c.3568C>T (p.R1190W) alteration is located in exon 1 (coding exon 1) of the C2orf16 gene. This alteration results from a C to T substitution at nucleotide position 3568, causing the arginine (R) at amino acid position 1190 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
