Description

In patients with classic GSD type Ib (GSD1B; 232220), Veiga-da-Cunha et al. (1999) reported a T-to-C transition at nucleotide 415 in exon 8 of the G6PT1 gene, resulting in an arg415-to-ter (R415X) substitution.

Description

This sequence change creates a premature translational stop signal (p.Arg415*) in the SLC37A4 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 15 amino acid(s) of the SLC37A4 protein. This variant is present in population databases (rs121908979, gnomAD 0.03%). This premature translational stop signal has been observed in individual(s) with glycogen storage disease 1b (PMID: 10482962, 10931421, 15059622, 21575371). This variant is also known as 1412C>T. ClinVar contains an entry for this variant (Variation ID: 6934). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant disrupts the C-terminus of the SLC37A4 protein. Other variant(s) that disrupt this region (p.Lys426Glnfs*4) have been observed in individuals with SLC37A4-related conditions (PMID: 24385852). This suggests that this may be a clinically significant region of the protein. For these reasons, this variant has been classified as Pathogenic.

Description

Variant summary: SLC37A4 c.1243C>T (p.Arg415X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 4.4e-05 in 249028 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in SLC37A4 causing Glycogen Storage Disease Type Ib (4.4e-05 vs 0.0012), allowing no conclusion about variant significance. c.1243C>T has been reported in the literature in individuals affected with Glycogen Storage Disease Type Ib (e.g. Veiga-da-Cunha_1999, Kojima_2004). Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Both laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
