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]

NM_001080463.1:c.7967G>A in the DYNC2H1 gene has an allele frequency of 0.006 in Ashkenazi Jewish subpopulation in the gnomAD database. Pathogenic computational verdict because pathogenic predictions from DANN, DEOGEN2, EIGEN, FATHMM-MKL, M-CAP, MutationAssessor, MutationTaster and SIFT. Zhang et al reported a Caucasian patient with short-rib polydactyly syndromes type I (c.[7268C>A];[7967G>T], in trans) and a Latino patient with asphyxiating thoracic dystrophy ([5984C>T];[7967G>T], in trans)(PMID: 29068549). However, the pathogenicity of c.7268C>A and 5984C>T was uncertain. We interpret it as a variant of uncertain significance favor of likely pathogenic. ACMG/AMP criteria applied: PP3, PP4. -
