Genes affected
DYNC2I2 (HGNC:28296): (dynein 2 intermediate chain 2) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. Defects in this gene are a cause of short-rib thoracic dysplasia 11 with or without polydactyly. [provided by RefSeq, Mar 2014]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM1
In a repeat WD 4 (size 40) in uniprot entity DC2I2_HUMAN there are 5 pathogenic changes around while only 1 benign (83%) in NM_052844.4
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 9-128633958-T-G is Pathogenic according to our data. Variant chr9-128633958-T-G is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 446624.Status of the report is no_assertion_criteria_provided, 0 stars.
BP4
Computational evidence support a benign effect (MetaRNN=0.24052885). . Strength limited to SUPPORTING due to the PP5.
