The c.1771C>T (p.R591C) alteration is located in exon 7 (coding exon 6) of the KANK3 gene. This alteration results from a C to T substitution at nucleotide position 1771, causing the arginine (R) at amino acid position 591 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
