Genes affected

DYNC2H1 (HGNC:2962): (dynein cytoplasmic 2 heavy chain 1) This gene encodes a large cytoplasmic dynein protein that is involved in retrograde transport in the cilium and has a role in intraflagellar transport, a process required for ciliary/flagellar assembly. Mutations in this gene cause a heterogeneous spectrum of conditions related to altered primary cilium function and often involve polydactyly, abnormal skeletogenesis, and polycystic kidneys. Alternative splicing results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Jan 2010]

The DYNC2H1 c.6265A>G variant is predicted to result in the amino acid substitution p.Asn2089Asp. This variant was reported in the compound heterozygous state in at least one individual with asphyxiating thoracic dystrophy (Supplementary Table S2, Zhang et al. 2018. PubMed ID: 29068549). This variant is reported in 0.00089% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-103049880-A-G). This variant is interpreted as likely pathogenic. -
