Collection Method: clinical testing

The c.365C>T (p.P122L) alteration is located in exon 7 (coding exon 3) of the IQCF3 gene. This alteration results from a C to T substitution at nucleotide position 365, causing the proline (P) at amino acid position 122 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
