Rare syndromic craniosynostosis or isolated multisuture synostosis
Gene: TMEM251
Added new-gene-name tag, new approved HGNC gene symbol for TMEM251 is LYSET.
The OMIM entry for this gene is OMIM:619332, which has been cross-checked with Ensembl, HGNC and G2P. Hence, gene-checked tag has been added.Created: 17 Oct 2023, 11:50 a.m. | Last Modified: 17 Oct 2023, 11:50 a.m.

Whole-exome sequencing identified two homozygous variants c.133C>T/ p.Arg45Trp (absent from gnomAD) and c.215dupA/ p.Tyr72Ter (2 alleles in gnomAD, annotated as pathogenic in ClinVar), in two families. Immunofluorescence and confocal studies show that the p.Arg45Trp mutant TMEM251 protein was targeted less efficiently to the Golgi complex compared to wildtype protein (PMID:33252156).
