Genes affected
LORICRIN (HGNC:6663): (loricrin cornified envelope precursor protein) This gene encodes loricrin, a major protein component of the cornified cell envelope found in terminally differentiated epidermal cells. Mutations in this gene are associated with Vohwinkel's syndrome and progressive symmetric erythrokeratoderma, both inherited skin diseases. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.08557418).
BS2
High AC in GnomAdExome4 at 14 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 23, 2023The c.175T>C (p.Y59H) alteration is located in exon 2 (coding exon 1) of the LOR gene. This alteration results from a T to C substitution at nucleotide position 175, causing the tyrosine (Y) at amino acid position 59 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
