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]

Autosomal dominant childhood-onset proximal spinal muscular atrophy with contractures Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 15, 2022Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. This variant has not been reported in the literature in individuals affected with BICD2-related conditions. This variant is present in population databases (rs763836233, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Gln843*) in the BICD2 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 13 amino acid(s) of the BICD2 protein. -
