Variant 1-59346397-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_018291.5(FGGY):c.464A>G(p.Glu155Gly) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000118 in 1,611,142 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E155K) has been classified as Uncertain significance.

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]

Ambry Genetics

Jun 23, 2023

The c.464A>G (p.E155G) alteration is located in exon 4 (coding exon 3) of the FGGY gene. This alteration results from a A to G substitution at nucleotide position 464, causing the glutamic acid (E) at amino acid position 155 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
