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 made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BP6
Variant 15-89645125-G-T is Benign according to our data. Variant chr15-89645125-G-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 263140.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=2, Likely_benign=3}.
BP7
Synonymous conserved (PhyloP=1.32 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0000558 (81/1452772) while in subpopulation AFR AF= 0.00131 (44/33478). AF 95% confidence interval is 0.00101. There are 1 homozygotes in gnomad4_exome. There are 37 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
