Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.64C>G (p.L22V) alteration is located in exon 3 (coding exon 2) of the SLC17A2 gene. This alteration results from a C to G substitution at nucleotide position 64, causing the leucine (L) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
