Collection Method:clinical testing

The c.758C>T (p.P253L) alteration is located in exon 9 (coding exon 6) of the FOXJ3 gene. This alteration results from a C to T substitution at nucleotide position 758, causing the proline (P) at amino acid position 253 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
