Invitae RCV000400667 SCV000964060 likely pathogenic Galactosylceramide beta-galactosidase deficiency 2018-09-20 criteria provided, single submitter clinical testing This sequence change affects codon 65 of the GALC mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the GALC protein. This variant also falls at the last nucleotide of exon 1 of the GALC coding sequence, which is part of the consensus splice site for this exon. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has been observed in individuals affected with late-onset globoid-cell leukodystrophy (PMID: 8940268, 9005874, 23197103). This variant is also known as c.147G>C in the literature. ClinVar contains an entry for this variant (Variation ID: 280959). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Experimental studies have shown that this silent change results in aberrant splicing of the GALC primary transcript (PMID: 8940268). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
