15. LSM7 variants involving key amino acids for LSM complex function cause a neurodevelopmental disorder with leukodystrophy and cerebellar atrophy.

Abstract

Cerebellar atrophy and hypoplasia are usually identified on MRI performed on children presenting signs of cerebellar ataxias, developmental delay, and intellectual disability. These signs can be associated with hypo- or de-myelinating leukodystrophies. A recent study reported two cases: one child diagnosed with leukodystrophy and cerebellar atrophy, harboring a homozygous variant in LSM7, and another who died in utero, presumed to have another homozygous variant in LSM7, based on the parents' genotype. LSM7 encodes a subunit of the LSM complex, involved in pre-RNA maturation and mRNA degradation. Consequently, it has been suggested as a strong candidate disease gene. This hypothesis was supported by functional investigations of the variants. Here, we report a patient with neurodevelopmental defects, leukodystrophy, and cerebellar atrophy, harboring compound heterozygous missense variants in the LSM7 gene. One of these variants is the same as the one carried by the first case reported previously. The other one is at the same position as the variant potentially carried by the second case reported previously. Based on comparable neuroimaging, clinical features, and the involvement of the same amino acids previously demonstrated as key for LSM complex function, we confirm that LSM7 disruption causes a neurodevelopmental disorder characterized by leukodystrophy and cerebellar atrophy., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2024 The Author(s).

Abstract

Objective: Terminal 6q deletion is a rare genetic condition associated with a neurodevelopmental disorder characterized by intellectual disability and structural brain anomalies. Interestingly, a similar phenotype is observed in patients harboring pathogenic variants in the DLL1 gene. Our study aimed to further characterize the prenatal phenotype of this syndrome as well as to attempt to establish phenotype-genotype correlations., Method: We collected ultrasound findings from 22 fetuses diagnosed with a pure 6qter deletion. We reviewed the literature and compared our 22 cases with 14 fetuses previously reported as well as with patients with heterozygous DLL1 pathogenic variants., Results: Brain structural alterations were observed in all fetuses. The most common findings (>70%) were cerebellar hypoplasia, ventriculomegaly, and corpus callosum abnormalities. Gyration abnormalities were observed in 46% of cases. Occasional findings included cerebral heterotopia, aqueductal stenosis, vertebral malformations, dysmorphic features, and kidney abnormalities., Conclusion: This is the first series of fetuses diagnosed with pure terminal 6q deletion. Based on our findings, we emphasize the prenatal sonographic anomalies, which may suggest the syndrome. Furthermore, this study highlights the importance of chromosomal microarray analysis to search for submicroscopic deletions of the 6q27 region involving the DLL1 gene in fetuses with these malformations., (© 2021 John Wiley & Sons Ltd.)
