The c.7393C>T (p.P2465S) alteration is located in exon 10 (coding exon 9) of the ZFHX2 gene. This alteration results from a C to T substitution at nucleotide position 7393, causing the proline (P) at amino acid position 2465 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
