Genes affected

FUCA1 (HGNC:4006): (alpha-L-fucosidase 1) The protein encoded by this gene is a lysosomal enzyme involved in the degradation of fucose-containing glycoproteins and glycolipids. Mutations in this gene are associated with fucosidosis (FUCA1D), which is an autosomal recessive lysosomal storage disease. A pseudogene of this locus is present on chr 2.[provided by RefSeq, Oct 2009]

Uncertain significance, criteria provided, single submitter	clinical testing	Genomic Research Center, Shahid Beheshti University of Medical Sciences	Aug 07, 2018	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Aug 03, 2022	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 308 of the FUCA1 protein (p.Arg308His). This variant is present in population databases (rs372537257, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with FUCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 587455). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
