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]

Submissions by phenotype
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 11, 2023 | The c.301G>A (p.E101K) alteration is located in exon 2 (coding exon 2) of the BICD2 gene. This alteration results from a G to A substitution at nucleotide position 301, causing the glutamic acid (E) at amino acid position 101 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
Autosomal dominant childhood-onset proximal spinal muscular atrophy with contractures Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 28, 2023 | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 101 of the BICD2 protein (p.Glu101Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BICD2-related conditions. ClinVar contains an entry for this variant (Variation ID: 541286). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt BICD2 function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
