Genes affected
FGGY (HGNC:25610): (FGGY carbohydrate kinase domain containing) This gene encodes a protein that phosphorylates carbohydrates such as ribulose, ribitol, and L-arabinitol. Genome-wide association studies in some populations have found an association between polymorphisms in this gene and sporadic amyotrophic lateral sclerosis, but studies of other populations have not been able to replicate this association. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 28, 2023The c.68G>A (p.R23H) alteration is located in exon 2 (coding exon 1) of the FGGY gene. This alteration results from a G to A substitution at nucleotide position 68, causing the arginine (R) at amino acid position 23 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
