Collection Method: clinical testing

The c.1481A>T (p.N494I) alteration is located in exon 15 (coding exon 15) of the TLE1 gene. This alteration results from a A to T substitution at nucleotide position 1481, causing the asparagine (N) at amino acid position 494 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
