Ambry Genetics

Nov 22, 2023

The c.556C>T (p.L186F) alteration is located in exon 5 (coding exon 4) of the SNX25 gene. This alteration results from a C to T substitution at nucleotide position 556, causing the leucine (L) at amino acid position 186 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
