Genes affected

MDGA1 (HGNC:19267): (MAM domain containing glycosylphosphatidylinositol anchor 1) This gene encodes a glycosylphosphatidylinositol (GPI)-anchored cell surface glycoprotein that is expressed predominantly in the developing nervous system. In addition to possessing several cell adhesion molecule-like domains, the mature protein has six Ig-like domains, a single fibronectin type III domain, a MAM domain and a C-terminal GPI-anchoring site. Studies in other mammals suggest this protein plays a role in cell adhesion, migration, and axon guidance and, in the developing brain, neuronal migration. In humans, this gene is associated with bipolar disorder and schizophrenia. [provided by RefSeq, Oct 2016]

The c.2470C>G (p.L824V) alteration is located in exon 14 (coding exon 14) of the MDGA1 gene. This alteration results from a C to G substitution at nucleotide position 2470, causing the leucine (L) at amino acid position 824 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
