Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 3P and 4B. PP2PP3_ModerateBS2

The NM_001278628.2(CRNKL1):​c.1394G>A​(p.Arg465Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000217 in 1,614,010 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R465G) has been classified as Uncertain significance.

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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 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: 2.5211 (below the threshold of 3.09).
PP3
MetaRNN computational evidence supports a deleterious effect, 0.894
BS2
High AC in GnomAdExome4 at 32 AD gene.
