Ambry Genetics

Nov 29, 2023

The c.101C>T (p.P34L) alteration is located in exon 1 (coding exon 1) of the FAM219B gene. This alteration results from a C to T substitution at nucleotide position 101, causing the proline (P) at amino acid position 34 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
