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.1853T>C (p.F618S) alteration is located in exon 19 (coding exon 19) of the SLC44A4 gene. This alteration results from a T to C substitution at nucleotide position 1853, causing the phenylalanine (F) at amino acid position 618 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
