Genes affected

GALC (HGNC:4115): (galactosylceramidase) This gene encodes a lysosomal protein which hydrolyzes the galactose ester bonds of galactosylceramide, galactosylsphingosine, lactosylceramide, and monogalactosyldiglyceride. Mutations in this gene have been associated with Krabbe disease, also known as globoid cell leukodystrophy. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

Galactosylceramide beta-galactosidase deficiency

Uncertain:3

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 02, 2021	This sequence change replaces alanine with valine at codon 8 of the GALC protein (p.Ala8Val). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and valine. This variant is present in population databases (rs376511103, ExAC 0.1%). This missense change has been observed in individual(s) with clinical features of GALC-related conditions (PMID: 26795590). This variant is also known as c.-26C>T. 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. -
