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 Benign. Variant got -9 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=0.01785478).
BP6
Variant 2-121367677-G-A is Benign according to our data. Variant chr2-121367677-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3033199.Status of the report is no_assertion_criteria_provided, 0 stars.
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000794 (116/1461712) while in subpopulation AMR AF= 0.00163 (73/44724). AF 95% confidence interval is 0.00133. There are 1 homozygotes in gnomad4_exome. There are 47 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 29 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
