Genes affected

KIF12 (HGNC:21495): (kinesin family member 12) This gene encodes a member of the kinesin superfamily of microtubule-associated molecular motors with functions related to the microtubule cytosekelton. Members of this superfamily play important roles in intracellular transport and cell division. A similar protein in mouse functions in the beta cell antioxidant signaling cascade, acting as a scaffold for the transcription factor specificity protein 1 (Sp1). Mice that lack this gene exhibit beta cell oxidative stress resulting in hypoinsulinemic glucose intolerance. [provided by RefSeq, Jul 2016]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.18762976).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000905 (132/1459120) while in subpopulation AMR AF= 0.000499 (22/44092). AF 95% confidence interval is 0.000337. 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. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.1357C>G (p.P453A) alteration is located in exon 15 (coding exon 13) of the KIF12 gene. This alteration results from a C to G substitution at nucleotide position 1357, causing the proline (P) at amino acid position 453 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
