Genes affected

BICD2 (HGNC:17208): (BICD cargo adaptor 2) This gene is one of two human homologs of Drosophila bicaudal-D and a member of the Bicoid family. It has been implicated in dynein-mediated, minus end-directed motility along microtubules. It has also been reported to be a phosphorylation target of NIMA related kinase 8. Two alternative splice variants have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.066199094).

BP6

Variant 9-92715225-C-T is Benign according to our data. Variant chr9-92715225-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 1792145.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000105 (16/152384) while in subpopulation AFR AF = 0.000337 (14/41600). AF 95% confidence interval is 0.000203. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 16 AD gene.
