Genes affected

BICD1 (HGNC:1049): (BICD cargo adaptor 1) This gene encodes an adaptor protein that belongs to the bicaudal D family of dynein cargo adaptors. The encoded protein acts as an intracellular cargo transport cofactor that regulates the microtubule-based loading of cargo onto the dynein motor complex. It also controls dynein motor activity and coordination. It has a domain architecture consisting of coiled-coil domains at the N- and C-termini that are highly conserved in other family members. Naturally occurring mutations in this gene are associated with short telomere length and emphysema. [provided by RefSeq, Aug 2017]

The c.678T>G (p.I226M) alteration is located in exon 4 (coding exon 4) of the BICD1 gene. This alteration results from a T to G substitution at nucleotide position 678, causing the isoleucine (I) at amino acid position 226 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
