Description

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. This variant disrupts the p.Ala367 amino acid residue in SLC37A4. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 10923042, 12444104, 18835800, 32300528; SOURCE: 10518030). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with SLC37A4-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 367 of the SLC37A4 protein (p.Ala367Pro).
