The c.527C>G (p.A176G) alteration is located in exon 3 (coding exon 2) of the ZKSCAN7 gene. This alteration results from a C to G substitution at nucleotide position 527, causing the alanine (A) at amino acid position 176 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
