Chromosome Breakage Disorders v1.8 MARS Zornitza Stark gene: MARS was added
gene: MARS was added to Chromosome Breakage Disorders. Sources: Literature
Mode of inheritance for gene: MARS was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: MARS were set to 33909043
Phenotypes for gene: MARS were set to Trichothiodystrophy, MONDO:0018053
Review for gene: MARS was set to RED
Added comment: Bi-allelic ariants in this gene are associated with interstitial and liver disease.

PMID: 33909043 - Botta et al 2021 - using WES/WGS analysis of 34 unsolved cases with multi-system phenotypes, but with hair alterations that are typical of trichothiodystrophy but no reported photosensitivity, they identified a homozygous variant in one Italian patient (c.1201G > A (p.Val401Me) that is very rare (gnomAD frequency 0.00001414). Functional studies suggest that the variant affects gene product stability.

Although chromosome breakage is unlikely to be the underlying mechanism, included in this panel for completeness with a Red rating (one individual reported).
