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]

BIN3 links:

CCAR2 (HGNC:23360): (cell cycle and apoptosis regulator 2) Enables RNA polymerase II complex binding activity and enzyme inhibitor activity. Involved in several processes, including regulation of cellular protein metabolic process; regulation of signal transduction; and regulation of transcription, DNA-templated. Located in several cellular components, including mitochondrial matrix; nucleoplasm; and spindle. Part of DBIRD complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.686C>T (p.S229F) alteration is located in exon 9 (coding exon 9) of the BIN3 gene. This alteration results from a C to T substitution at nucleotide position 686, causing the serine (S) at amino acid position 229 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
