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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.018916994).

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00000479 (7/1461002) while in subpopulation MID AF= 0.000347 (2/5758). AF 95% confidence interval is 0.000061. There are 0 homozygotes in gnomad4_exome. There are 2 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.3982G>T (p.V1328L) alteration is located in exon 13 (coding exon 13) of the CAMSAP1 gene. This alteration results from a G to T substitution at nucleotide position 3982, causing the valine (V) at amino acid position 1328 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
