Genes affected
ASTN1 (HGNC:773): (astrotactin 1) Astrotactin is a neuronal adhesion molecule required for glial-guided migration of young postmitotic neuroblasts in cortical regions of developing brain, including cerebrum, hippocampus, cerebellum, and olfactory bulb (Fink et al., 1995).[supplied by OMIM, Jun 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.3179G>A (p.R1060H) alteration is located in exon 19 (coding exon 19) of the ASTN1 gene. This alteration results from a G to A substitution at nucleotide position 3179, causing the arginine (R) at amino acid position 1060 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
