The c.788C>T (p.S263L) alteration is located in exon 3 (coding exon 1) of the ZNF391 gene. This alteration results from a C to T substitution at nucleotide position 788, causing the serine (S) at amino acid position 263 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
