Among individuals with DFSP in the 3 cohorts, germline P/LP variants were also identified in the following genes (1 case per gene): ACD (HGNC ID: 25070), ERCC5 (HGNC ID: 3437), ERCC1 (HGNC ID: 3433), DOCK8 (HGNC ID: 19191), GBA1 (HGNC ID: 4177), ATM (HGNC ID: 795), MUTYH (HGNC ID: 7527), TP53 (HGNC ID: 11998), RECQL4 (HGNC ID: 9949), and COL7A1 (HGNC ID: 2214) (Table 2). This evidence concerns the gene ERCC1 and dermatofibrosarcoma protuberans.
