Ambry Genetics

Dec 13, 2022

The c.703C>T (p.R235C) alteration is located in exon 7 (coding exon 7) of the SIDT2 gene. This alteration results from a C to T substitution at nucleotide position 703, causing the arginine (R) at amino acid position 235 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
