In addition to variants in genes with known gene-disease associations, 5 de novo variants absent in gnomAD in 5 novel genes also identified in 5 unrelated individuals: - ARID3A (missense variant, REVEL 0.72) - PIK3C3 (missense, mechanistically not thought to be an obvious candidate gene for CdLS) - MCM7 (LoF variant, gene linked with cohesin complex) - MIS18BP1 (LoF variant, this individual also had a de novo intragenic deletion in PUF60) - WDR18 (missense variant, weak in silico, REVEL 0.268) Sources: Literature |

Arina Puzriakova gene: MCM7 was added gene: MCM7 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: MCM7 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: MCM7 were set to 33654309; 34059554 Phenotypes for gene: MCM7 were set to Meier-Gorlin syndrome; Microcephaly; Intellectual disability; Lipodystrophy; Adrenal insufficiency Review for gene: MCM7 was set to AMBER Added comment: MCM7 is a component of the MCM complex, a DNA helicase which is essential for DNA replication. Other components have been linked to disease with phenotypes including microcephaly and ID. MCM7 is not associated with any phenotype in OMIM or G2P at present. ------ Currently there are 3 unrelated pedigrees in literature with different biallelic MCM7 variants associated with disease (see below). Although there is some functional data in support of variant-level deleteriousness or gene-level pathogenicity, the clinical gestalt is very different between the 3 families. - PMID: 33654309 (2021) - Two unrelated individuals with different compound het variants in MCM7 but disparate clinical features. One patient had typical Meier-Gorlin syndrome (including growth retardation, microcephaly, congenital lung emphysema, absent breast development, microtia, facial dysmorphism) whereas the second case had a multi-system disorder with neonatal progeroid appearance, lipodystrophy and adrenal insufficiency. While small at birth, the second patient did not demonstrate reduced stature or microcephaly at age 14.5 years. Both individuals had normal neurodevelopment. Functional studies using patient-derived fibroblasts demonstrate that the identified MCM7 variants were deleterious at either transcript or protein levels and through interfering with MCM complex formation, impact efficiency of S phase progression. - PMID: 34059554 (2021) - Homozygous missense variant identified in three affected individuals from a consanguineous family with severe primary microcephaly, severe ID and behavioural abnormalities. Knockdown of Mcm7 in mouse neuroblastoma cells lead to reduced cell viability and proliferation with increased apoptosis, which were rescued by overexpression of wild-type but not mutant MCM7.
