Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.590A>T (p.D197V) alteration is located in exon 6 (coding exon 6) of the SLC44A3 gene. This alteration results from a A to T substitution at nucleotide position 590, causing the aspartic acid (D) at amino acid position 197 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
