Ambry Genetics

Feb 28, 2023

The c.151A>T (p.I51F) alteration is located in exon 2 (coding exon 1) of the TSKU gene. This alteration results from a A to T substitution at nucleotide position 151, causing the isoleucine (I) at amino acid position 51 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
