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]

The c.670C>G (p.Q224E) alteration is located in exon 4 (coding exon 4) of the MIA3 gene. This alteration results from a C to G substitution at nucleotide position 670, causing the glutamine (Q) at amino acid position 224 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
