Genes affected

KRT17 (HGNC:6427): (keratin 17) This gene encodes the type I intermediate filament chain keratin 17, expressed in nail bed, hair follicle, sebaceous glands, and other epidermal appendages. Mutations in this gene lead to Jackson-Lawler type pachyonychia congenita and steatocystoma multiplex. [provided by RefSeq, Aug 2008]

Our verdict: Pathogenic. The variant received 10 ACMG points.

PM1

In a hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 1 uncertain in NM_000422.3

PM2

Very rare variant in population databases, with high coverage;

PP3

MetaRNN computational evidence supports a deleterious effect, 0.991

PP5

Variant 17-41624214-A-G is Pathogenic according to our data. Variant chr17-41624214-A-G is described in ClinVar as Pathogenic. ClinVar VariationId is 14598.Status of the report is criteria_provided_single_submitter, 1 stars.
