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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2024The c.929G>A (p.R310H) alteration is located in exon 8 (coding exon 8) of the CAMSAP3 gene. This alteration results from a G to A substitution at nucleotide position 929, causing the arginine (R) at amino acid position 310 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
