Collection Method: clinical testing

The c.367C>T (p.P123S) alteration is located in exon 5 (coding exon 5) of the AFAP1L1 gene. This alteration results from a C to T substitution at nucleotide position 367, causing the proline (P) at amino acid position 123 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
