The c.52A>C (p.T18P) alteration is located in exon 2 (coding exon 1) of the ZFHX4 gene. This alteration results from a A to C substitution at nucleotide position 52, causing the threonine (T) at amino acid position 18 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
