Zornitza Stark changed review comment from: Two unrelated families reported with CMT type 2. Affected individuals in both families exhibited severe vocal fold paresis, a rare feature of peripheral nerve disease that can be life-threatening. Studies of mutant protein posttranslational modification and localization indicated that the mutations (p.Ser577Arg, p.Ser650Pro) impair protein glycosylation and reduce JAG1 cell surface expression. Mice harboring heterozygous CMT2-associated mutations exhibited mild peripheral neuropathy, and homozygous expression resulted in embryonic lethality by midgestation. Pre-existing rat model. Sources: Literature; to: Association with Alagille is very well established. Two unrelated families reported with CMT type 2.

Chern Lim changed review comment from: Luxan 2013 (PMID: 23314057): - V943F, seg with LVNC in 1 fam, (gnomADv2: 43 hets). - R530X, seg with LVNC in 1 fam, (gv2: 13 hets). Li 2018 (PMID: 30322850): - in 4 CHD patients: p.Q237H (gv2v3 absent), p.W271G (gv2v3 absent), p.S520R (v2 5 hets) and p.T312Kfs*55 (NMD-pred, absent but many comparables in gnomAD). - HEK293T cells transfection studies showed: T312Kfs*55 and W271G strongly impaired MIB1 function on substrate ubiquitination, while Q237H and S520R had slight or no obvious changes. Interaction between MIB1 and JAG1 is severely interrupted by p.T312Kfs*55 and p.W271G, but not really in the other 2 missense. - Overexpression of wt or mutant in zebrafish all resulted in dysmorphic pheno, therefore not informative. DCM-association = none by Clingen (9/4/2020), ref Luxan 2013 and other pprs, and mentioned gnomAD had too many LoF variants. De Ligt 2012 (PMID: 23033978): de novo R174H (gnomADv2: 7 hets), indvl with severe ID who also has a de novo R47* in WAC (an AD ID gene with LoF established, variant is P in ClinVar), no other pt-specific pheno provided. Kaplanis 2021 (PMID: 33057194): Developmental disorders paper. - 2 missense variants, de novo: 18-19383967-G-A (p.Glu491Lys, gv2 1 het, gv3 absent, GeneDx), 18-19378124-C-T (Thr391Ile, gv2v3 absent, DDD, de novo, no mention of heart pheno). - Of 6 PTVs, 4 had at least 10 hets each in gnomADv2.; to: Luxan 2013 (PMID: 23314057): - V943F, seg with LVNC in 1 fam, (gnomADv2: 43 hets). - R530X, seg with LVNC in 1 fam, (gv2: 13 hets).
