Genes affected

SLC1A5 (HGNC:10943): (solute carrier family 1 member 5) The SLC1A5 gene encodes a sodium-dependent neutral amino acid transporter that can act as a receptor for RD114/type D retrovirus (Larriba et al., 2001 [PubMed 11781704]).[supplied by OMIM, Jan 2011]

SLC1A5 links:

FKRP (HGNC:17997): (fukutin related protein) This gene encodes a protein which is targeted to the medial Golgi apparatus and is necessary for posttranslational modification of dystroglycan. Mutations in this gene have been associated with congenital muscular dystrophy, cognitive disability, and cerebellar cysts. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Oct 2008]

Collection Method: clinical testing

The c.1394G>A (p.R465Q) alteration is located in exon 8 (coding exon 8) of the SLC1A5 gene. This alteration results from a G to A substitution at nucleotide position 1394, causing the arginine (R) at amino acid position 465 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
