The c.724C>G (p.Q242E) alteration is located in exon 4 (coding exon 4) of the YY1AP1 gene. This alteration results from a C to G substitution at nucleotide position 724, causing the glutamine (Q) at amino acid position 242 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
