Genes affected

SLC17A5 (HGNC:10933): (solute carrier family 17 member 5) This gene encodes a membrane transporter that exports free sialic acids that have been cleaved off of cell surface lipids and proteins from lysosomes. Mutations in this gene cause sialic acid storage diseases, including infantile sialic acid storage disorder and and Salla disease, an adult form. [provided by RefSeq, Jul 2008]

Pathogenic:3

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 14, 2023	For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 56551). This premature translational stop signal has been observed in individual(s) with SLC17A5-related conditions (PMID: 10947946). This variant is present in population databases (rs386833987, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Leu336Trpfs*14) in the SLC17A5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC17A5 are known to be pathogenic (PMID: 10581036, 10947946, 15172001). -
