Genes affected
KIF7 (HGNC:30497): (kinesin family member 7) This gene encodes a cilia-associated protein belonging to the kinesin family. This protein plays a role in the sonic hedgehog (SHH) signaling pathway through the regulation of GLI transcription factors. It functions as a negative regulator of the SHH pathway by preventing inappropriate activation of GLI2 in the absence of ligand, and as a positive regulator by preventing the processing of GLI3 into its repressor form. Mutations in this gene have been associated with various ciliopathies. [provided by RefSeq, Oct 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.011151433).
BP6
Variant 15-89652882-G-A is Benign according to our data. Variant chr15-89652882-G-A is described in ClinVar as [Benign]. Clinvar id is 129418.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00393 (598/152342) while in subpopulation AFR AF = 0.0134 (556/41580). AF 95% confidence interval is 0.0125. There are 3 homozygotes in GnomAd4. There are 295 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position FAILED quality control check.
BS2
High Homozygotes in GnomAd4 at 3 AR,Digenic gene
