| Identified Mutation |
c.515dupC (p.P173Sfs*43) |
| Remarks |
Clinically affected; onset of symptoms at 59 years of age; diagnosed by specialist at 60 years of age; whole exome sequencing revealed an insertion in an intron with a region of sequence variant identity on chromosome 9 between 35,060,302 and 35,066,579 (region includes VCP gene); co-segregation analysis results and confirmation by automated Sanger sequencing revealed a heterozygous mutation in the HSPB8 gene: c.515dupC (p.P173Sfs*43) in exon CDS 3; positive family history: this mutation is also present in the affected son (lymph GM26095, fibro GM26096) and affected brothers (fibro GM26579, lymph GM26099); heterozygous variants of uncertain significance (VUS) that are present in both the affected son and affected brother are: CCDC78 c.986T>C (p.I329T), MUSK c.43C>A (p.L15M), and TRIM32 c.1223G>A (p.R408H); assistive device: walking cane; unaffected son (GM26099); at-risk half-sister (GM26100); see fibro (GM26098); pedigree and family history in PMID 31403083. |
