The c.1561C>T (p.R521C) alteration is located in exon 16 (coding exon 16) of the GK5 gene. This alteration results from a C to T substitution at nucleotide position 1561, causing the arginine (R) at amino acid position 521 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
