BMC Med Genomics . 2023 Jun; 16(1):143. PMID: 37344844
Bi-allelic variants in the mitochondrial arginyl-transfer RNA synthetase (RARS2) gene have been involved in early-onset encephalopathies classified as pontocerebellar hypoplasia (PCH) type 6 and in epileptic encephalopathy. A variant (NM_020320.3:c.-2A ...

Riedhammer K, Burgemeister A, Cantagrel V, Amiel J, Siquier-Pernet K, Boddaert N, et al.
Hum Mol Genet . 2022 May; 31(18):3083-3094. PMID: 35512351
Background: TASP1 encodes an endopeptidase activating histone methyltransferases of the KMT2 family. Homozygous loss-of-function variants in TASP1 have recently been associated with Suleiman-El-Hattab syndrome. We report six individuals with Suleiman-El-Hattab...

Eur J Hum Genet . 2022 Apr; 30(6):712-720. PMID: 35388186
Highly identical segmental duplications (SDs) account for over 5% of the human genome and are enriched in the short arm of the chromosome 16. These SDs are susceptibility factors for...
