Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4BS1_Supporting

The NM_015447.4(CAMSAP1):​c.4262C>A​(p.Pro1421His) variant causes a missense change. The variant allele was found at a frequency of 0.0000167 in 1,613,870 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P1421T) 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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.3022974).
BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000197 (3/152316) while in subpopulation EAS AF= 0.00058 (3/5174). AF 95% confidence interval is 0.000157. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
