Red List (low evidence)

- Single patient with complex spastic paraplegia with ataxia, intellectual disability, developmental delay and seizures, but without microcephaly de novo for a heterozygous variant (.969_969+2delGGT) which ablates a canonical splice site
- Patient fibroblasts showed reduced (~30%) aminoacylation activity
- Yeast complementation studies using mutant plasmid did not generate viable haploid strains (loss of function)
- Co-transfection of WT and mutant S.pombe SARS resulted in growth defect, suggesting a dominant negative defect

note that the gene is also known as SARS1

Summary - 2 unrelated families with overlapping ID phenotype, and supporting in vitro and patient cell assays.
PMID: 28236339 - an Iranian family (distantly related) segregating a homozygous missense (c.514G>A, p.Asp172Asn) with moderate ID, microcephaly, ataxia, speech impairment, and aggressive behaviour. Also, supporting in vitro functional assays demonstrating altered protein function.
PMID: 34570399 - a consanguineous Turkish family segregating a homozygous missense (c.638G>T, p.(Arg213Leu)) with developmental delay, central deafness, cardiomyopathy, and metabolic decompensation during fever leading to death. Also, reduced protein level and enzymatic activity in patient cells.
