Variant summary

Our verdict is Benign. The variant received -17 ACMG points: 0P and 17B. BP4BP6_Very_StrongBS1BS2

The NM_001003800.2(BICD2):c.485G>A(p.Arg162His) variant causes a missense change. The variant allele was found at a frequency of 0.0000167 in 1,613,556 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 Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R162C) has been classified as Likely benign.

Genes affected

BICD2 (HGNC:17208): (BICD cargo adaptor 2) This gene is one of two human homologs of Drosophila bicaudal-D and a member of the Bicoid family. It has been implicated in dynein-mediated, minus end-directed motility along microtubules. It has also been reported to be a phosphorylation target of NIMA related kinase 8. Two alternative splice variants have been described. [provided by RefSeq, Jul 2008]

Computational evidence support a benign effect (MetaRNN=0.42328689).

BP6

Variant 9-92722777-C-T is Benign according to our data. Variant chr9-92722777-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 565772.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000144 (21/1461854) while in subpopulation SAS AF = 0.000128 (11/86258). AF 95% confidence interval is 0.0000712. There are 0 homozygotes in GnomAdExome4. There are 17 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High AC in GnomAd4 at 6 AD gene.
