Genes affected

DNMBP (HGNC:30373): (dynamin binding protein) This gene encodes a protein belonging to the guanine nucleotide exchange factor family, and which regulates the configuration of cell junctions. It contains multiple binding sites for dynamin and thus links dynamin to actin regulatory proteins. Polymorphisms in this gene have been linked to Alzheimer's disease in some populations, though there are conflicting reports of such linkages in other populations. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

Ambry Genetics

Feb 09, 2022

The c.2222A>G (p.N741S) alteration is located in exon 4 (coding exon 3) of the DNMBP gene. This alteration results from a A to G substitution at nucleotide position 2222, causing the asparagine (N) at amino acid position 741 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
