dbSNP rs200614421: DYNC2H1:p.Arg2656His (chr11-103199355-G-A) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 6P and 5B. PM1PM2PM5BP4_StrongBP6

The NM_001377.3(DYNC2H1):c.7967G>A(p.Arg2656His) variant causes a missense change. The variant allele was found at a frequency of 0.000141 in 1,612,254 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2656C) has been classified as Likely pathogenic.

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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PM1

In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 2 uncertain in NM_001377.3

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr11-103199354-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 446533.

BP4

Computational evidence support a benign effect (MetaRNN=0.01862505).

BP6

Variant 11-103199355-G-A is Benign according to our data. Variant chr11-103199355-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 446620.
