The c.556C>G (p.Q186E) alteration is located in exon 6 (coding exon 6) of the WDFY2 gene. This alteration results from a C to G substitution at nucleotide position 556, causing the glutamine (Q) at amino acid position 186 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
