| Remarks |
Unaffected father of affected proband; LCL is GM27980; clinical exome sequencing test results were negative for the pathogenic heterozygous de novo CHAMP1 variant c.542_543delCT (p.Ser181CysfsX5) harbored by affected daughter, GM27963 (fibro) and GM27967 (LCL); though this parent does not have the pathogenic variant, the possibility of germline mosaicism cannot be excluded; positive for the Factor V Leiden variant not detected in the affected daughter. |
