Ambry Genetics

Nov 27, 2023

The c.118C>T (p.R40W) 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 118, causing the arginine (R) at amino acid position 40 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
