Genes affected

CAMSAP3 (HGNC:29307): (calmodulin regulated spectrin associated protein family member 3) Enables actin filament binding activity and microtubule minus-end binding activity. Involved in several processes, including microtubule cytoskeleton organization; regulation of organelle organization; and zonula adherens maintenance. Located in cytoplasm; nucleoplasm; and zonula adherens. Colocalizes with centrosome and microtubule minus-end. [provided by Alliance of Genome Resources, Apr 2022]

The c.737G>A (p.R246H) alteration is located in exon 7 (coding exon 7) of the CAMSAP3 gene. This alteration results from a G to A substitution at nucleotide position 737, causing the arginine (R) at amino acid position 246 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
