Ambry Genetics

May 17, 2023

The c.881A>T (p.N294I) alteration is located in exon 5 (coding exon 4) of the SPATC1L gene. This alteration results from a A to T substitution at nucleotide position 881, causing the asparagine (N) at amino acid position 294 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
