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: Benign. The variant received -18 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_052844.4

BP4

Computational evidence support a benign effect (MetaRNN=0.014472216).

BP6

Variant 9-128634837-C-T is Benign according to our data. Variant chr9-128634837-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 474844.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00266 (405/152354) while in subpopulation SAS AF = 0.00786 (38/4832). AF 95% confidence interval is 0.00589. There are 1 homozygotes in GnomAd4. There are 197 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 21 AR gene
