Genes affected

AP1B1 (HGNC:554): (adaptor related protein complex 1 subunit beta 1) Adaptor protein complex 1 is found at the cytoplasmic face of coated vesicles located at the Golgi complex, where it mediates both the recruitment of clathrin to the membrane and the recognition of sorting signals within the cytosolic tails of transmembrane receptors. This complex is a heterotetramer composed of two large, one medium, and one small adaptin subunit. The protein encoded by this gene serves as one of the large subunits of this complex and is a member of the adaptin protein family. This gene is a candidate meningioma gene. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

The c.2683A>G (p.M895V) alteration is located in exon 21 (coding exon 20) of the AP1B1 gene. This alteration results from a A to G substitution at nucleotide position 2683, causing the methionine (M) at amino acid position 895 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
