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]

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Mar 01, 2018	The p.Leu3272Ile variant (rs200342335) was reported in a 5-days old infant with Short-rib thoracic dysplasia 3 (MIM: 613091) who was bi-allelic with a truncating DYNC2H1 variant (Meng 2017). This variant is listed in the Genome Aggregation Database (gnomAD) with a frequency of 0.7 percent in the African population (identified on 171 out of 23,438 chromosomes, including 1 homozygote). The leucine at position 3,272 is highly conserved up to Hawaiian sea urchin considering 28 species (Alamut v2.10) and computational analyses of the p.Leu3272Ile variant on protein structure and function indicates a deleterious effect (SIFT: damaging, PolyPhen-2: possibly damaging). Altogether, there is not enough evidence to classify the p.Leu3272Ile variant with certainty. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
