Ambry Genetics

Feb 06, 2023

The c.1541C>T (p.P514L) alteration is located in exon 8 (coding exon 8) of the LONRF2 gene. This alteration results from a C to T substitution at nucleotide position 1541, causing the proline (P) at amino acid position 514 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
