Added comment: Associated with Spondyloepimetaphyseal dysplasia, sponastrime type MIM#271510 (AR) in OMIM.

PMID: 30773277 - Burrage et al 2019 - identified, using WES or Sanger sequencing, compound heterozygous variants in TONSL in 9 individuals (8 families) with SPONASTRIME dysplasia. 4 other probands with SPONASTRIME dysplasia did not have biallelic variants in TONSL or in MMS22L, but two of them did have a single heterozygous variants in TONSL. The authors say they cannot exclude deep intronic, promotor variants or large intragenic rearrangements/deletions in these patients. An additional 4 individuals (3 families) with short stature of varied severity and spondylometaphyseal dysplasia with or without immunologic and hematologic abnormalities were also found to have compound heterozygous variants in TONSL.

PMID: 30773278 - Chang et al 2019 - Using WES they identified homozygous or compound heterozygous TONSL variants in 10 of 13 individuals (9 families) with SPONASTRIME dysplasia.

PMID: 32959051 - Micale et al 2020 - report a 9-year-old Italian girl with typical SPONASTRIME dysplasia who was found to have two novel missense variants in TONSL. Each parent was heterozygous for one of the variants. Both variants were found to be very rare in the gnomad database. Patient-derived fibroblasts show increased levels of spontaneous chromosomal breaks, reduced cell proliferation and enhanced apoptosis.
