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]

CLASP1 links:

RNU4ATAC (HGNC:34016): (RNA, U4atac small nuclear) The small nuclear RNA (snRNA) encoded by this gene is part of the U12-dependent minor spliceosome complex. In addition to the encoded RNA, this ribonucleoprotein complex consists of U11, U12, U5, and U6atac snRNAs. The U12-dependent spliceosome acts on approximately 700 specific introns in the human genome. Defects in this gene are a cause of microcephalic osteodysplastic primordial dwarfism type 1 (MOPD).

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP5

Variant 2-121530932-C-T is Pathogenic according to our data. Variant chr2-121530932-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 692041.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.28). . Strength limited to SUPPORTING due to the PP5.

BS2

High AC in GnomAd4 at 22 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
