The c.196A>G (p.T66A) alteration is located in exon 1 (coding exon 1) of the C2orf16 gene. This alteration results from a A to G substitution at nucleotide position 196, causing the threonine (T) at amino acid position 66 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
