The c.1166T>C (p.I389T) alteration is located in exon 11 (coding exon 11) of the RNGTT gene. This alteration results from a T to C substitution at nucleotide position 1166, causing the isoleucine (I) at amino acid position 389 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
