Description

In a Japanese patient with glycogen storage disease Ib (GSD1B; 232220), Kure et al. (1998) found compound heterozygosity for the W118R mutation (602671.0003) and a G-to-A substitution within a consensus splicing donor site, which resulted in deletion of 170 bp (nucleotides 148-317) and involved the initiation methionine codon.

In a German patient with GSD Ic (GSD1C; 232240), Janecke et al. (1999) identified the same mutation in homozygous state. Genomic sequencing revealed a homozygous 317+1G-T substitution within a consensus splicing donor site.

Description

This sequence change affects a donor splice site in intron 3 of the SLC37A4 gene. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with SLC37A4-related conditions (PMID: 9675154, 10323254). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 6932). Studies have shown that this variant results in a deletion of 170bp from exon 4 and introduces a premature termination codon (PMID: 9675154). The resulting mRNA is expected to undergo nonsense-mediated decay. For these reasons, this variant has been classified as Pathogenic.
