The c.1547C>T (p.S516L) alteration is located in exon 6 (coding exon 4) of the ZNF343 gene. This alteration results from a C to T substitution at nucleotide position 1547, causing the serine (S) at amino acid position 516 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
