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.

The c.1876T>C (p.Y626H) alteration is located in exon 10 (coding exon 10) of the SLC2A13 gene. This alteration results from a T to C substitution at nucleotide position 1876, causing the tyrosine (Y) at amino acid position 626 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
