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]

NM_000153.3(GALC):c.1586C>T(T529M, aka T513M) is classified as likely pathogenic in the context of Krabbe disease. Sources cited for classification include the following: PMID 23197103, 21824559, 9266397, 9338580, 20886637 and 23128445. Classification of NM_000153.3(GALC):c.1586C>T(T529M, aka T513M) is based on the following criteria: This variant has been observed more frequently in patients with clinical diagnoses than in healthy populations. Please note: this variant was assessed in the context of healthy population screening. -

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.010%). Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 26865610). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.76; 3Cnet: 0.66). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000370073). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 529 of the GALC protein (p.Thr529Met). This variant is present in population databases (rs200960659, gnomAD 0.02%). This missense change has been observed in individual(s) with Krabbe disease (PMID: 9266397, 9338580, 20135576, 20886637, 21824559, 23128445, 23197103). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is also known as c.1538C>T (p.T513M). ClinVar contains an entry for this variant (Variation ID: 370073). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt GALC protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects GALC function (PMID: 26865610, 27126738). For these reasons, this variant has been classified as Pathogenic. -

The GALC c.1586C>T variant is predicted to result in the amino acid substitution p.Thr529Met. This variant was reported in the homozygous and compound heterozygous state in multiple individuals with Krabbe disease (Xie et al. 2019. PubMed ID: 31885218; Table S2, Dong et al. 2020. PubMed ID: 32005694; Adam et al. 1993. PubMed ID: 20301416; Tappino et al. 2010. PubMed ID: 20886637; reported as p.Thr513Met in Wenger et al. 1997. PubMed ID: 9338580). This variant is reported in 0.019% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
