Genes affected

SLC36A1 (HGNC:18761): (solute carrier family 36 member 1) This gene encodes a member of the eukaryote-specific amino acid/auxin permease (AAAP) 1 transporter family. The encoded protein functions as a proton-dependent, small amino acid transporter. This gene is clustered with related family members on chromosome 5q33.1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.421C>A (p.R141S) alteration is located in exon 6 (coding exon 5) of the SLC36A1 gene. This alteration results from a C to A substitution at nucleotide position 421, causing the arginine (R) at amino acid position 141 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
