Ambry Genetics

Sep 22, 2022

The c.521C>T (p.T174I) alteration is located in exon 4 (coding exon 3) of the TMIGD1 gene. This alteration results from a C to T substitution at nucleotide position 521, causing the threonine (T) at amino acid position 174 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
