Collection Method: clinical testing

The c.1160C>T (p.T387I) alteration is located in exon 7 (coding exon 6) of the SLC16A4 gene. This alteration results from a C to T substitution at nucleotide position 1160, causing the threonine (T) at amino acid position 387 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
