Genes affected
MIA3 (HGNC:24008): (MIA SH3 domain ER export factor 3) Enables cargo receptor activity. Involved in several processes, including COPII-coated vesicle cargo loading; cell migration involved in sprouting angiogenesis; and regulation of leukocyte migration. Located in endoplasmic reticulum exit site and endoplasmic reticulum membrane. Is integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.425G>A (p.G142E) alteration is located in exon 4 (coding exon 4) of the MIA3 gene. This alteration results from a G to A substitution at nucleotide position 425, causing the glycine (G) at amino acid position 142 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
