All patients had learning difficulties with 8 labelled as intellectually disabled (mild-moderate). Other clinical features included anomalies of craniofacial, musculoskeletal, brain, renal and cardiac development. WDR44 is a negative regulator of ciliogenesis. Increased binding is hypothesised to underlie the pathogenicity of WDR44 variants identified in this cohort. Functional data supported impaired ciliogenesis initiation in patient fibroblasts and a zebrafish model. A zebrafish model recapitulated the human phenotype when morphants expressed WDR44 L668S, D669N, S764F, G782C, H839R, and R733* variants. Of note, D648G or N840S did not recapitulate the phenotype in the zebrafish model. The studies supported a GoF mechanism, but the authors could not rule out that LoF of WDR44 contributes to the ciliopathy-like phenotype observed, because protein expression data was only available for a limited number of patients.

WES found de novo heterozygous missense variants in KIF5B encoding kinesin-1 heavy chain. All variants involved conserved amino acids in or close to the ATPase activity-related motifs in the catalytic motor domain of the KIF5B protein. No functional studies of variants. Previously 2 animal model experiments showed that loss of function of KIF5B can cause kyphomelic dysplasia. First, chondrocyte-specific knockout of Kif5b in mice was shown to produce a disorganized growth plate, leading to bone deformity. Second, double mutants disrupting the two zebrafish kif5b caused abnormal skeletal morphogenesis and the curvature of Meckel's and ceratohyal cartilages. Sources: Literature |

PMID 31337748: Somatic variant in this gene found in one individual with focal cortical dysplasia. --- 3 individuals from two families with heterozygous RHEB variants. Two siblings carried the c.110 C > T (p.Pro37Leu) variant, and a sporadic individual carried the c.202 T>C (p.Ser68Pro) allele. All 3 individuals had short stature (−2 to −3 SD) and early brain overgrowth with pronounced macrocephaly during childhood (+2.5/+3 SD). They had severe to profound ID with hypotonia, as well as autism spectrum disorder. 2 of 3 individuals were reported to have epilepsy. In a zebrafish model, overexpression of RHEB produced megalencephaly, supporting a hyperactivating effect. This is supported in mice where loss of RHEB activity does not cause an overt neurological phenotype Single individual with somatic variants in this gene and focal cortical dysplasia also reported.

| Fetal anomalies v0.4305 | VPS50 |
Chirag Patel gene: VPS50 was added gene: VPS50 was added to Fetal anomalies. Sources: Expert list Mode of inheritance for gene: VPS50 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: VPS50 were set to PMID: 34037727 Phenotypes for gene: VPS50 were set to Neurodevelopmental disorder with microcephaly, seizures, and neonatal cholestasis , MIM#619685 Review for gene: VPS50 was set to AMBER Added comment: Schneeberger et al (2021 - PMID: 34037727) describe the phenotype of 2 unrelated individuals with biallelic VPS50 variants. Common features included transient neonatal cholestasis, failure to thrive, severe DD with failure to achieve milestones (last examination at 2y and 2y2m respectively), postnatal microcephaly, seizures (onset at 6m and 25m) and irritability. There was corpus callosum hypoplasia on brain imaging. Both individuals were homozygous for variants private to each family (no/not known consanguinity applying to each case). The first individual was homozygous for a splicing variant (NM_017667.4:c.1978-1G>T) and had a similarly unaffected sister deceased with no available DNA for testing. The other individual was homozygous for an in-frame deletion (c.1823_1825delCAA / p.(Thr608del)). VPS50 encodes a critical component of the endosome-associated recycling protein (EARP) complex, which functions in recycling endocytic vesicles back to the plasma membrane [OMIM based on Schindler et al]. The complex contains VPS50, VPS51, VPS52, VPS53, the three latter also being components of GARP (Golgi-associated-retrograde protein) complex. GARP contains VPS54 instead of VPS50 and is required for trafficking of proteins to the trans-golgi network. Thus VPS50 (also named syndetin) and VPS54 function in the EARP and GARP complexes, to define directional movement of their endocytic vesicles [OMIM based on Schindler et al]. The VPS50 subunit is required for recycling of the transferrin receptor. As discussed by Schneeberger et al (refs provided in text): - VPS50 has a high expression in mouse and human brain as well as throughout mouse brain development. - Mice deficient for Vps50 have not been reported. vps50 knockdown in zebrafish results in severe developmental defects of the body axis. Knockout mice for other proteins of the EARP/GARP complex (e.g. Vps52, 53 and 54) display embryonic lethality. Studies performed by Schneeberger et al included: - Transcript analysis for the 1st variant demonstrated skipping of ex21 (in patient derived fabriblasts) leading to an in frame deletion of 81 bp (r.1978_2058del) with predicted loss of 27 residues (p.Leu660_Leu686del). - Similar VPS50 mRNA levels but significant reduction of protein levels (~5% and ~8% of controls) were observed in fibroblasts from patients 1 and 2. Additionally, significant reductions in the amounts of VPS52 and VPS53 protein levels were observed despite mRNA levels similar to controls. Overall, this suggested drastic reduction of functional EARP complex levels. - Lysosomes appeared to have similar morphology, cellular distribution and likely unaffected function in patient fibroblasts. - Transferrin receptor recycling was shown to be delayed in patient fibroblasts suggestive of compromise of endocytic-recycling function. As the authors comment, the phenotype of both individuals with biallelic VPS50 variants overlaps with the corresponding phenotype reported in 15 subjects with biallelic VPS53 or VPS51 mutations notably, severe DD/ID, microcephaly and early onset epilepsy, CC anomalies. Overall, for this group, they propose the term "GARP and/or EARP deficiency disorders". There is no VPS50-associated phenotype in OMIM or G2P. SysID includes VPS50 among the ID candidate genes.

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. PMID: 33057194 - Has been identified as a gene with significant de novo enrichment in a large trio study from the Deciphering Developmental Disorders study. 11 de novo variants (1 frameshift, 2 missense, 2 splice acceptor, 1 splice donor, 5 stopgain) identified in ~10,000 cases with developmental disorders (no other phenotype info provided).

They found de novo and inherited variants in GDF11. gdf11 mutant zebrafish showed craniofacial abnormalities and body segmentation defects that matched some patient phenotypes. Expression of the patients’ variants in the fly showed that one nonsense variant in GDF11 is a severe loss-of-function (LOF) allele whereas the missense variants are partial LOF variants.
