Variant summary

Our verdict is Benign. Variant got -16 ACMG points: 4P and 20B. PM1PM5BP4_StrongBP6_Very_StrongBA1

The NM_000526.5(KRT14):c.1237G>A(p.Ala413Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0125 in 1,613,478 control chromosomes in the GnomAD database, including 354 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A413P) has been classified as Uncertain significance.

Genes affected

KRT14 (HGNC:6416): (keratin 14) This gene encodes a member of the keratin family, the most diverse group of intermediate filaments. This gene product, a type I keratin, is usually found as a heterotetramer with two keratin 5 molecules, a type II keratin. Together they form the cytoskeleton of epithelial cells. Mutations in the genes for these keratins are associated with epidermolysis bullosa simplex. At least one pseudogene has been identified at 17p12-p11. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -16 ACMG points.

PM1

In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_000526.5

PM5

Other missense variant is known to change same aminoacid residue: Variant chr17-41583272-C-G is described in Lovd as [Pathogenic].

BP4

Computational evidence support a benign effect (MetaRNN=0.052458495).

BP6

Variant 17-41583272-C-T is Benign according to our data. Variant chr17-41583272-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 66319.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BA1

GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.0562 is higher than 0.05.
