Ambry Genetics

Oct 13, 2023

The c.463G>T (p.A155S) alteration is located in exon 5 (coding exon 4) of the KATNBL1 gene. This alteration results from a G to T substitution at nucleotide position 463, causing the alanine (A) at amino acid position 155 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
