Gene: SS18L1

I don't know

ClinGen has curated as LIMITED:

There are 5 variants (one nonsense, three missense, and one in-frame del) that have been reported in 5 probands in 3 publications (PMIDs: 23708140, 24360741, 31522742) that are included in this curation, one of which was not scored due to the patient harboring a variant in another ALS-causing gene and a high minor allele frequency in population databases. ALS-associated SS18L1 variants are suggested to dysregulate neuronal function by inhibiting dendrite outgrowth and microglial activation through a dominant-negative mechanism, however there is an absence of functional data from primary tissue of SS18L1 mutation carriers. This gene-disease relationship is also supported by experimental evidence (mouse models, expression, and protein interactions; PMIDs: 30976389, 14716005, 23708140). CREST knockout (Crest +/− ) and Q394X knock-in mice generated through CRISPR/Cas9 system displayed deficits in motor coordination and partially recapitulated ALS phenotypes (PMID: 30976389). In summary, there is limited evidence to support this gene-disease relationship. Although more evidence is needed to support a causal role, no convincing evidence has emerged that contradicts the gene-disease relationship.
