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]

The c.905T>C (p.L302P) alteration is located in exon 9 (coding exon 8) of the SLC36A1 gene. This alteration results from a T to C substitution at nucleotide position 905, causing the leucine (L) at amino acid position 302 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
