Genes affected

BIN3 (HGNC:1054): (bridging integrator 3) The product of this gene is a member of the BAR domain protein family. The encoded protein is comprised solely of a BAR domain which is predicted to form coiled-coil structures and proposed to mediate dimerization, sense and induce membrane curvature, and bind small GTPases. BAR domain proteins have been implicated in endocytosis, intracellular transport, and a diverse set of other processes. [provided by RefSeq, Jul 2008]

The c.184A>T (p.I62L) alteration is located in exon 5 (coding exon 5) of the BIN3 gene. This alteration results from a A to T substitution at nucleotide position 184, causing the isoleucine (I) at amino acid position 62 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
