Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002265978 SCV002548147 likely pathogenic Lamellar ichthyosis 2022-05-04 criteria provided, single submitter clinical testing Variant summary: ALOX12B c.416_417delCC (p.Ala139GlufsX37) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been reported in affected individuals (HGMD). The variant was absent in 250612 control chromosomes (gnomAD). c.416_417delCC has been reported in the literature in a homozygous individual affected with congenital ichthyosis, however no further phenotype details were provided (Hotz_2021). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One submitter has provided clinical-significance assessments for this variant in ClinVar after 2014 without evidence for independent evaluation, and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic.
