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 made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), BICD2. . Gene score misZ 2.205 (greater than the threshold 3.09). Trascript score misZ 3.1082 (greater than threshold 3.09). GenCC has associacion of gene with autosomal dominant childhood-onset proximal spinal muscular atrophy with contractures.

BP4

Computational evidence support a benign effect (MetaRNN=0.027107626).

BP6

Variant 9-92715282-C-A is Benign according to our data. Variant chr9-92715282-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 579572.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000986 (15/152206) while in subpopulation AMR AF= 0.00072 (11/15282). AF 95% confidence interval is 0.000403. There are 0 homozygotes in gnomad4. There are 10 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.

BS2

High AC in GnomAd4 at 15 AD gene.

Ambry Genetics

Feb 24, 2021

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
