Genes affected

KIFBP (HGNC:23419): (kinesin family binding protein) This gene encodes a kinesin family member 1 binding protein that is characterized by two tetratrico peptide repeats. The encoded protein localizes to the mitochondria and may be involved in regulating transport of the mitochondria. Mutations in this gene are associated with Goldberg-Shprintzen megacolon syndrome.

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.006440878).

BP6

Variant 10-68988900-A-G is Benign according to our data. Variant chr10-68988900-A-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 158698.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 = 0.00605 (922/152352) while in subpopulation AFR AF = 0.0212 (882/41590). AF 95% confidence interval is 0.02. There are 8 homozygotes in GnomAd4. There are 417 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 8 AR gene
