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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -17 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), BICD2. . Gene score misZ 2.205 (greater than the threshold 3.09). Trascript score misZ 3.1082 (greater than threshold 3.09). GenCC has associacion of gene with autosomal dominant childhood-onset proximal spinal muscular atrophy with contractures.
BP4
Computational evidence support a benign effect (MetaRNN=0.14769518).
BP6
Variant 9-92719164-T-C is Benign according to our data. Variant chr9-92719164-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 474259.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.00012 (175/1458938) while in subpopulation NFE AF= 0.000142 (158/1111950). AF 95% confidence interval is 0.000124. There are 0 homozygotes in gnomad4_exome. There are 75 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 8 AD gene.

Inborn genetic diseases Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsNov 04, 2019This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
