Genes affected

TAMALIN (HGNC:18707): (trafficking regulator and scaffold protein tamalin) This gene encodes a protein that functions as a molecular scaffold, linking receptors, including group 1 metabotropic glutamate receptors, to neuronal proteins. The encoded protein contains conserved domains, including a leucine zipper sequence, PDZ domain and a C-terminal PDZ-binding motif. Alternately spliced transcript variants have been observed for this gene.[provided by RefSeq, Dec 2012]

The c.176T>C (p.L59P) alteration is located in exon 1 (coding exon 1) of the GRASP gene. This alteration results from a T to C substitution at nucleotide position 176, causing the leucine (L) at amino acid position 59 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
