Whole exome sequencing discloses heterozygous variants in the DNAJC21 and EFL1 genes but not in SRP54 in 6 out of 16 patients with Shwachman-Diamond Syndrome carrying biallelic SBDS mutations.
Title: Whole exome sequencing discloses heterozygous variants in the DNAJC21 and EFL1 genes but not in SRP54 in 6 out of 16 patients with Shwachman-Diamond Syndrome carrying biallelic SBDS mutations.
we report biallelic mutations in EFL1 in 3 unrelated individuals with clinical features of SDS. Cellular defects in these individuals include impaired ribosomal subunit joining and attenuated global protein translation as a consequence of defective eIF6 eviction.
Title: EFL1 mutations impair eIF6 release to cause Shwachman-Diamond syndrome.
the effect of SBDS mutations on the interaction with EFL1were tested, and showed that all tested mutations disrupted the binding to EFL1.
Title: Interaction of the GTPase Elongation Factor Like-1 with the Shwachman-Diamond Syndrome Protein and Its Missense Mutations.
Mutations in EFL1 clinically manifest phenotypes of infantile pancytopenia, exocrine pancreatic insufficiency and skeletal anomalies. Mutant EFL1 proteins do not promote the release of yeast cytoplasmic Tif6 from the 60S subunit, likely preventing the formation of mature ribosomes.
Title: Mutations in EFL1, an SBDS partner, are associated with infantile pancytopenia, exocrine pancreatic insufficiency and skeletal anomalies in aShwachman-Diamond like syndrome.
Association of Elongation Factor-like 1 (EFL1) GTPase to SBDS did not modify the affinity for GTP but dramatically decreased that for GDP by increasing the dissociation rate of the nucleotide.
Title: Defective Guanine Nucleotide Exchange in the Elongation Factor-like 1 (EFL1) GTPase by Mutations in the Shwachman-Diamond Syndrome Protein.
Upon EFL1 binding, SBDS is repositioned around helix 69, thus facilitating a conformational switch in EFL1 that displaces eIF6 by competing for an overlapping binding site on the 60S ribosomal subunit.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
