The c.559T>G (p.S187A) alteration is located in exon 7 (coding exon 6) of the ZNF740 gene. This alteration results from a T to G substitution at nucleotide position 559, causing the serine (S) at amino acid position 187 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
