Ambry Genetics

Sep 11, 2024

The c.263C>A (p.T88N) alteration is located in exon 1 (coding exon 1) of the KIAA1468 gene. This alteration results from a C to A substitution at nucleotide position 263, causing the threonine (T) at amino acid position 88 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
