Genes affected
CRNKL1 (HGNC:15762): (crooked neck pre-mRNA splicing factor 1) The crooked neck (crn) gene of Drosophila is essential for embryogenesis and is thought to be involved in cell cycle progression and pre-mRNA splicing. A protein encoded by this human locus has been found to localize to pre-mRNA splicing complexes in the nucleus and is necessary for pre-mRNA splicing. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2013]
CFAP61 (HGNC:15872): (cilia and flagella associated protein 61) Predicted to be involved in cilium movement and cilium organization. Predicted to be located in axoneme and motile cilium. Predicted to colocalize with radial spoke stalk. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.87994 (below the threshold of 3.09). Trascript score misZ: 1.501 (below the threshold of 3.09).
BP4
Computational evidence support a benign effect (MetaRNN=1.8984517E-6).
BA1
GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.693 is higher than 0.05.
