Ambry Genetics

Nov 21, 2022

The c.164C>T (p.P55L) alteration is located in exon 2 (coding exon 1) of the LLPH gene. This alteration results from a C to T substitution at nucleotide position 164, causing the proline (P) at amino acid position 55 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
