Ambry Genetics

Jul 19, 2022

The c.1286C>T (p.P429L) alteration is located in exon 4 (coding exon 2) of the FAM222B gene. This alteration results from a C to T substitution at nucleotide position 1286, causing the proline (P) at amino acid position 429 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
