Genes affected

SDR9C7 (HGNC:29958): (short chain dehydrogenase/reductase family 9C member 7) This gene encodes a protein with similarity to the short-chain dehydrogenase/reductase (SDR) family but has not been shown to have retinoid or dehydrogenase activities. [provided by RefSeq, Apr 2010]

Variant summary: SDR9C7 c.888delT (p.Val297X) results in a premature termination codon, predicted to cause a truncation of the encoded protein by 16 amino acids, reducing the protein from 313 to 297 amino acids in length. Truncation of the SDR9C7 protein is a commonly known mechanism for disease. The variant allele was found at a frequency of 4e-06 in 251012 control chromosomes. To our knowledge, no occurrence of c.888delT in individuals affected with Lamellar Ichthyosis and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
