NM_000421.5:c.1683_1684insAGCTCCGGCGGCGGATACGGCGGCGGCAGCAGC

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM4

The NM_000421.5(KRT10):​c.1683_1684insAGCTCCGGCGGCGGATACGGCGGCGGCAGCAGC​(p.Ser561_Ser562insSerSerGlyGlyGlyTyrGlyGlyGlySerSer) variant causes a conservative inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000213 in 1,406,290 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected
KRT10 (HGNC:6413): (keratin 10) This gene encodes a member of the type I (acidic) cytokeratin family, which belongs to the superfamily of intermediate filament (IF) proteins. Keratins are heteropolymeric structural proteins which form the intermediate filament. These filaments, along with actin microfilaments and microtubules, compose the cytoskeleton of epithelial cells. Mutations in this gene are associated with epidermolytic hyperkeratosis. This gene is located within a cluster of keratin family members on chromosome 17q21. [provided by RefSeq, Jul 2008]
KRT10-AS1 (HGNC:28305): (KRT10 antisense RNA 1) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
