Collection Method: clinical testing

The c.1636G>T (p.A546S) alteration is located in exon 9 (coding exon 9) of the SLC2A13 gene. This alteration results from a G to T substitution at nucleotide position 1636, causing the alanine (A) at amino acid position 546 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
