Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2024The c.1777G>A (p.V593I) alteration is located in exon 17 (coding exon 17) of the GFPT2 gene. This alteration results from a G to A substitution at nucleotide position 1777, causing the valine (V) at amino acid position 593 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
