Genes affected

CLASP1 (HGNC:17088): (cytoplasmic linker associated protein 1) CLASPs, such as CLASP1, are nonmotor microtubule-associated proteins that interact with CLIPs (e.g., CLIP170; MIM 179838). CLASP1 is involved in the regulation of microtubule dynamics at the kinetochore and throughout the spindle (Maiato et al., 2003 [PubMed 12837247]).[supplied by OMIM, Mar 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CLASP1. . Gene score misZ 3.6133 (greater than the threshold 3.09). GenCC has associacion of gene with complex neurodevelopmental disorder.

BP4

Computational evidence support a benign effect (MetaRNN=0.36505443).

BS2

High AC in GnomAdExome4 at 30 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.3895G>A (p.D1299N) alteration is located in exon 36 (coding exon 35) of the CLASP1 gene. This alteration results from a G to A substitution at nucleotide position 3895, causing the aspartic acid (D) at amino acid position 1299 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
