Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_015447.4(CAMSAP1):ā€‹c.3492T>Gā€‹(p.Cys1164Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000206 in 1,458,942 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C1164R) has been classified as Uncertain significance.

Genes affected
CAMSAP1 (HGNC:19946): (calmodulin regulated spectrin associated protein 1) Enables microtubule minus-end binding activity and spectrin binding activity. Involved in several processes, including neuron projection development; regulation of cell morphogenesis; and regulation of microtubule polymerization. Located in microtubule. Colocalizes with microtubule minus-end. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 01, 2023The c.3492T>G (p.C1164W) alteration is located in exon 11 (coding exon 11) of the CAMSAP1 gene. This alteration results from a T to G substitution at nucleotide position 3492, causing the cysteine (C) at amino acid position 1164 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
