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]

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Pro583Pro variant (rs777813587) does not alter the amino acid sequence of the BICD2 protein and computational splice site prediction algorithms do not predict a change in the nearest splice site or creation of a cryptic splice site (Alamut v2.10). This variant has not been reported in association with spinal muscular atrophy in medical literature or in gene specific variation databases. This variant is listed in the Genome Aggregation Database (gnomAD) with an overall population frequency of 0.003 percent (identified on 7 out of 244,732 chromosomes). Based on these observations, the p.Pro583Pro variant is likely to be benign. -
