The c.1339G>C (p.E447Q) alteration is located in exon 4 (coding exon 4) of the ZNF433 gene. This alteration results from a G to C substitution at nucleotide position 1339, causing the glutamic acid (E) at amino acid position 447 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
