Genes affected

SLC2A13 (HGNC:15956): (solute carrier family 2 member 13) Enables ATPase binding activity; myo-inositol:proton symporter activity; and protease binding activity. Involved in myo-inositol transport and positive regulation of amyloid-beta formation. Is integral component of plasma membrane. Part of cell body; cell periphery; and cell projection.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1372A>G (p.N458D) alteration is located in exon 7 (coding exon 7) of the SLC2A13 gene. This alteration results from a A to G substitution at nucleotide position 1372, causing the asparagine (N) at amino acid position 458 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
