Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1002G>A (p.M334I) alteration is located in exon 4 (coding exon 4) of the SLC2A13 gene. This alteration results from a G to A substitution at nucleotide position 1002, causing the methionine (M) at amino acid position 334 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
