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]

Sep 20, 2023

The c.712G>A (p.D238N) alteration is located in exon 8 (coding exon 8) of the GRASP gene. This alteration results from a G to A substitution at nucleotide position 712, causing the aspartic acid (D) at amino acid position 238 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
