Arina Puzriakova gene: MTSS1L was added gene: MTSS1L was added to Intellectual disability. Sources: Literature new-gene-name, Q4_22_rating tags were added to gene: MTSS1L. Mode of inheritance for gene: MTSS1L was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: MTSS1L were set to 36067766 Phenotypes for gene: MTSS1L were set to Global developmental delay; Intellectual disability; Ophthalmological anomalies; Microcephaly; Mild facial dysmorphisms Review for gene: MTSS1L was set to GREEN Added comment: Huang et al. 2022 (PMID: 36067766) reported five unrelated individuals with the same heterozygous de novo variant (c.2011C>T; p.Arg671Trp) in MTSS2 (formally known as MTSS1L). Linkage analysis was not performed but given the variants arose de novo and the mixed ethnicity of the affected individuals (4 European, 1 Chinese) a founder effect can be ruled out. Subjects displayed a shared phenotype of GDD and/or ID, ophthalmological anomalies (most commonly nystagmus), microcephaly (primary in 2, relative in 3) and shared mild facial dysmorphisms. The single adult patient also presented with seizures and optic atrophy. Functional studies showed the variant leads to a decrease in mRNA level but does not impact protein levels of MTSS2. However, a Drosophila model demonstrated that loss of the fly ortholog results in defects in locomotor and visual functions which were rescued by human MTSS2 and only partially rescued by the MTSS2 c.2011C>T variant. Overexpression of the c.2011C>T variant caused similar phenotypes as the LoF mutant indicating a possible dominant-negative effect. Sources: Literature |
