Ambry Genetics

Aug 21, 2023

The c.1271T>C (p.I424T) alteration is located in exon 11 (coding exon 11) of the SLC5A4 gene. This alteration results from a T to C substitution at nucleotide position 1271, causing the isoleucine (I) at amino acid position 424 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
