Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.1735G>A (p.G579R) 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 1735, causing the glycine (G) at amino acid position 579 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
