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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.957

Collection Method: clinical testing

The c.41G>T (p.G14V) alteration is located in exon 2 (coding exon 1) of the FGGY gene. This alteration results from a G to T substitution at nucleotide position 41, causing the glycine (G) at amino acid position 14 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
