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.

Ambry Genetics

Jan 23, 2024

The c.1636G>T (p.A546S) alteration is located in exon 9 (coding exon 9) of the SLC2A13 gene. This alteration results from a G to T substitution at nucleotide position 1636, causing the alanine (A) at amino acid position 546 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
