Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 12P and 1B. PM2PM5PP5_Very_StrongBP4

The NM_001080463.2(DYNC2H1):c.5971A>T(p.Met1991Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000248 in 1,613,456 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M1991K) 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: Pathogenic. The variant received 11 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr11-103177653-T-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 439632.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP5

Variant 11-103177652-A-T is Pathogenic according to our data. Variant chr11-103177652-A-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 6500.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.2005617). . Strength limited to SUPPORTING due to the PP5.
