• chr1-59321712-T-A
• rs1211776277
• NM_018291.5:c.163T>A

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_018291.5(FGGY):​c.163T>A​(p.Ser55Thr) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S55P) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: FGGY NM_018291.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.13
• Publications: 0 publications found

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 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
