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 Uncertain_significance. Variant got 0 ACMG points.

PP5

Variant 2-121530929-G-C is Pathogenic according to our data. Variant chr2-121530929-G-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 30182.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr2-121530929-G-C is described in Lovd as [Pathogenic].

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.3). . Strength limited to SUPPORTING due to the PP5.

BS2

High AC in GnomAdExome4 at 7 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant is located within the 5' stem-loop region of the RNU4ATAC RNA, which includes the 15.5K binding site and is important for spliceosome assembly (PMID: 32628740). A significant number of disease-associated RNU4ATAC variants are found in this region (PMID: 32628740, 30368667). Experimental studies have shown that this variant affects RNU4ATAC function (PMID: 32628740). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. ClinVar contains an entry for this variant (Variation ID: 30182). This variant has been observed in individual(s) with RNU4ATAC-related conditions (PMID: 21474761). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs181195449, gnomAD 0.007%). This variant occurs in the RNU4ATAC gene, which encodes an RNA molecule that does not result in a protein product. -
