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]

Collection Method: clinical testing

The c.361C>T (p.L121F) alteration is located in exon 7 (coding exon 7) of the BIN3 gene. This alteration results from a C to T substitution at nucleotide position 361, causing the leucine (L) at amino acid position 121 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
