Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 4P and 4B. PM5PP3_ModerateBS1

The NM_001320198.2(KRT86):c.353C>T(p.Ala118Val) variant causes a missense change involving the alteration of a conserved nucleotide. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A118E) has been classified as Pathogenic.

Genes affected

KRT86 (HGNC:6463): (keratin 86) This gene encodes a type II keratin protein, which heterodimerizes with type I keratins to form hair and nails. This gene is present in a cluster of related genes and pseudogenes on chromosome 12. Mutations in this gene have been observed in patients with the hair disease monilethrix.
