SLC5A2-related disorder Uncertain:1
The SLC5A2 c.395G>A variant is predicted to result in the amino acid substitution p.Arg132His. This variant was reported with a second SLC5A2 variant in an individual with glucosuria and inherited from an apparently unaffected mother (Calado et al 2006. PubMed ID: 16518345). This variant was also reported in an adult male with incidental glucosuria that was otherwise healthy (Kim KM et al 2016. PubMed ID: 28275387). The c.395G>A variant was also reported in a child and father with glucosuria, suggesting possible autosomal dominant inheritance (Yu L. et al. 2020. PubMed ID: 32111189). A different amino acid substitution at this position (p.Arg132Cys) has also been reported with a second SLC5A2 variant in at least two individuals with glucosuria (Wang et al. 2018. PubMed ID: 30593819; Hureaux et al. 2019. PubMed ID: 31672324). This variant is reported in 0.017% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/16-31497141-G-A). Although we suspect this variant could be pathogenic, at this time, the clinical significance and mode of inheritance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
