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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2023The c.206G>A (p.R69H) alteration is located in exon 1 (coding exon 1) of the GRASP gene. This alteration results from a G to A substitution at nucleotide position 206, causing the arginine (R) at amino acid position 69 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
