Collection Method: clinical testing

The c.368C>T (p.P123L) alteration is located in exon 4 (coding exon 4) of the FAM86C1 gene. This alteration results from a C to T substitution at nucleotide position 368, causing the proline (P) at amino acid position 123 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
