Genes affected

SLC44A4 (HGNC:13941): (solute carrier family 44 member 4) The protein encoded by this gene may be a sodium-dependent transmembrane transport protein involved in the uptake of choline by cholinergic neurons. Defects in this gene can cause sialidosis, a lysosomal storage disease. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2010]

The c.2096A>G (p.N699S) alteration is located in exon 21 (coding exon 21) of the SLC44A4 gene. This alteration results from a A to G substitution at nucleotide position 2096, causing the asparagine (N) at amino acid position 699 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
