The c.2192C>G (p.T731R) alteration is located in exon 9 (coding exon 8) of the KANK3 gene. This alteration results from a C to G substitution at nucleotide position 2192, causing the threonine (T) at amino acid position 731 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
