The c.586C>T (p.R196C) alteration is located in exon 7 (coding exon 6) of the ZNF317 gene. This alteration results from a C to T substitution at nucleotide position 586, causing the arginine (R) at amino acid position 196 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
