Added comment: Name: cysteinyl-tRNA synthetase 1; Symbol: CARS1 ; HGNC ID: 1493

Current Status: Not in R227 Panel. This gene was added to the DDG2P panel in March 2019 as a amber gene and the reviewer noted the following: "Microcephaly Developmental Delay and Brittle Hair and Nails. DDG2P Disease confidence: probable. DDG2P mode of pathogenicity/mutation consequence: loss of function. DDG2P mode of inheritance: biallelic." Proposed change: GREEN

The CARS1 genes was added to the DDG2P panel in March 2019 as an amber gene and the reviewer noted the following: "Microcephaly Developmental Delay and Brittle Hair and Nails. DDG2P Disease confidence: probable. DDG2P mode of pathogenicity/mutation consequence: loss of function. DDG2P mode of inheritance: biallelic."

In Kuo et al (2019) reported the identification of bi-allelic CARS1 variants in four affected individuals from three families with complex syndromes that include microcephaly, developmental delay, and brittle hair and nails.

Case 1: CARS1 c.1138C>T p.(Gln380Ter) and CARS1 c.1022G>A p.(Arg341His) Case 2 and 3 (related): CARS1 c.1076C>T p.(Ser359Leu) and CARS1 c.1199T>A p. (Leu400Gln)
Case 4: Homozygous CARS1 c.2061dup p.(Ser688fs).

In-silico analysis predict that the variants result in a truncated protein or affect a highly conserved amino acid. Immunoblot analysis using CARS antibodies on protein isolated from the patient’s fibroblast confirmed the presence of a stable truncated protein for c.1138C>T nonsense variant, while the amount of full-length CARS protein was significantly reduced for the c.2061dup frameshifting variant. A possible explanation for this result is the extreme 3’ location of the variant which could allow it to escape nonsense mediated decay. Analysis of the CARS protein from Case 4 showed no change in the level of full-length CARS protein. Yeast complementation studies indicate that the p.(Gln380Ter), p. (Leu400Gln) and p.(Ser688fs) variants prevented yeast cell growth, consistent with a loss-of-function effect. Severely reduced cell growth was observed with the p.(Arg341His) and p.(Ser359Leu) variants, aminoacylation assays showed that these variants reduce enzyme activity. These results all support that each variant results in loss of function.

This report confirms that individuals with two loss of function CARS1 variants are involved in multi-system, recessive disorder that includes microcephaly, developmental delay, and brittle hair and nails. Clinical phenotypes that overlap with TTD individuals.

Added comment: Name: threonyl-tRNA synthetase 1; Symbol: TARS1; HGNC ID: 11572

Current Status: Not in R227 Panel. This gene was added to the DDG2P panel in Sept 2019 as a amber gene and the reviwer noted the following: "Non-photosensitive trichothiodystrophy. Disease confidence rating in DDG2P: probable. DDG2P mutation consequence: loss of function. DDG2P allelic requirement: biallelic." Proposed change: GREEN

Supporting Evidence:
Theil et al (2021) published a multi-centre WES/WGS sequencing study which screened in a group of 24 NPS-TTD individuals with no molecular diagnosis. TTD18PV and TTD5VI are unrelated individuals initially diagnosed with TTD were found to have the following predicted pathogenic variants in the TARS1 gene:

TTD18PV: TARS1 c.826A>G p.(Lys276Glu) and TARS1 c.1912C>T p.(Arg638Ter)
TTD5VI: Homozygous TARS1 c.680T>C (p.Leu227Pro).

Testing of additional individuals with unresolved NPS-TTD by the authors did not identify any further bi-allelic variants suggesting in their cohort of 47, TARS1 variants account for 4% of NPS-TTD cases.

In-silico analysis suggest that missense variants result in amino acid substitutions that are close to the core catalytic domain of the protein which may affect its catalytic activity. Quantitative RT-PCR analysis showed only a slight reduction in total TARS mRNA levels in TTD18PV’s primary fibroblasts, while allelic-specific qRT-PCR analysis showed that 90% of the total TARS mRNA molecules are from the missense p.(Lys276Glu) TARS variant with the remaining only 10% from the c.1912C>T variant allele. Immunoblot analysis of whole-cell extracts from both patient’s fibroblasts revealed an approximate 20% reduction in the total cellular amount of full-length TARS. This is consistent with these missense variants causing protein instability.

Based on a total of 47 NPS-TTD individuals for bi-allelic TARS1 variants, the authors suggest that TARS1 variants account for 4% of NPS-TTD cases.

Added comment: 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).

Added comment: PMID: 33909043 - Botta et al 2021 - using WES or 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 2 unrelated cases carrying 4 potentially pathogenic variants in the AARS1 gene (previously known as AARSB. Both patients had very rare compound heterozygous missense variants. In one family there was an older affected sibling but segregation data was not available for either family.

Xeroderma pigmentosum, Trichothiodystrophy or Cockayne syndrome v2.10 GTF2E2 Arina Puzriakova Added comment: Comment on list classification: Four individuals from 3 different Moroccan families with the same homozygous variant (c.C559T) in the GTF2E2 gene have been identified who all presented with non-photosensitive trichothiodystrophy. Even though this likely represents a founder effect in this population, an additional patient from Asian origin has been identified with a distinct homozygous variant (c.448G>C), corroborating pertinence of GTF2E2 variants in trichothiodystrophy. Furthermore, studies on primary fibroblasts of patients harbouring the founder variant demonstrated a reduction in the cellular levels of both subunits of the transcription initiation factor TFIIE.

Overall this is sufficient evidence to promote this gene to Green at the next GMS panel update.
