RCV001003329 | SCV001161414 | pathogenic | Farber lipogranulomatosis | 2019-06-19 | criteria provided, single submitter | literature only | Variant c.290_292delTGG is pathogenic based on the following rationale. The patient described Muramatsu et al., 2002, DOI: 10.1023/A:1022047408477 was diagnosed with an intermediate form of Farber disease consistent with Type 2-3 Farber disease discussed in Gene Reviews (https://www.ncbi.nlm.nih.gov/books/NBK488189/). Homozygous c.290_292delTGG variants were identified in the ASAH1 gene. To characterize the effect of the mutation V96del on acid ceramidase (AC) activity, modified human AC cDNA was transiently expressed in COS-1 cells; the mutant AC activities were decreased to 37% of the wild-type value explaining the intermediate Farber disease phenotype and the variant's likely pathogenicity. |
