Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.777G>T (p.L259F) alteration is located in exon 3 (coding exon 3) of the SLC2A13 gene. This alteration results from a G to T substitution at nucleotide position 777, causing the leucine (L) at amino acid position 259 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
