Collection Method: clinical testing

The c.352G>A (p.A118T) alteration is located in exon 5 (coding exon 3) of the SLC14A1 gene. This alteration results from a G to A substitution at nucleotide position 352, causing the alanine (A) at amino acid position 118 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
