Ambry Genetics

Aug 02, 2022

The c.428C>T (p.T143I) alteration is located in exon 2 (coding exon 1) of the SIPA1L1 gene. This alteration results from a C to T substitution at nucleotide position 428, causing the threonine (T) at amino acid position 143 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
