Collection Method:clinical testing

The c.1739C>T (p.A580V) alteration is located in exon 10 (coding exon 10) of the SLC2A13 gene. This alteration results from a C to T substitution at nucleotide position 1739, causing the alanine (A) at amino acid position 580 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
