Added comment: PMID: 26056285
- Bilateral coloboma and rod-cone dystrophy with or without cataract in nine individuals of a five-generation family.
- Heterozygous n.37C>T segregates with the disease in all affected individuals.
- Functional analysis including transcriptome analysis showed this variant resulted in significant alterations of miR-204 targeting capabilities. In vivo injection, in medaka fish (Oryzias latipes), of the mutated miR-204 caused a phenotype consistent with that observed in the family.
- Authors suggested gain of function is the likely disease mechanism.

PMID: 37321975
- Four members of a three-generation family with early-onset chorioretinal dystrophy, heterozygous for n.37C>T.
- Additionally, four family members were shown to be affected by albinism resulting from biallelic pathogenic OCA2 variants.
- Haplotype analysis excluded relatedness with the family reported in PMID: 26056285.
- In silico analysis of the MIR204 n.37C>T variant reveals profound changes to its target mRNAs and suggests a gain-of-function mechanism of miR 204 variant.

Mendeliome v1.3 RDH11 Zornitza Stark edited their review of gene: RDH11: Added comment: 2nd case reported: 1 Chinese patient with retinitis pigmentosa, juvenile cataracts, intellectual disability, and myopathy. Trio-based WES and whole genomic CNV detection found compound heterozygous variants in RDH11 (p.Leu313Pro and c.75-3C>A) with biparental inheritance. Variant c.75-3C>A was confirmed to be a splice-site mutation by cDNA sequencing. It caused exon 2 skipping, resulting in a frameshift mutation and premature translation termination (p.Lys26Serfs*38). They found mislocalization of RDH11 protein in muscle cells of the patient by using immunofluorescence staining. Retinol dehydrogenase 11 (RDH11) is an 11-cis-retinol dehydrogenase that has a well-characterized, albeit auxiliary role in the retinoid cycle. Diseases caused by mutations in the RDH11 gene are very rare, and only one affected family with eye and intelligence involvement has been reported.; Changed rating: AMBER; Changed publications: 24916380, 15634683, 30731079, 18326732, 34988992

Added comment: 4 individuals from 2 unrelated consanguineous families (Turkish and Indian) reported with a homozygous missense and an NMD-predicted nonsense variant. Affected individuals had features of mucopolysaccharidosis such as short stature, coarse facial features and dysostosis multiplex. Urinary GAG excretion was normal by conventional methods, but LC-MS/MS in 2 individuals revealed an increase in specific dermatan sulfate-derived disaccharides. Functional studies showed reduced protein levels and reduced enzyme activity for the nonsense and missense variant respectively.

A mouse model also shows a mucopolysaccharidosis phenotype, albeit milder.

Rated green (2 families, functional evidence, mouse model).

Phenotypes for gene: CAMK4 were set to Intellectual disability; Autism; Behavioral abnormality; Abnormality of movement; Dystonia; Ataxia; Chorea; Myoclonus
Review for gene: CAMK4 was set to GREEN
Added comment: 3 publications by Zech et al (2018, 2020 - PMIDs : 30262571, 33098801, 33211350) provide clinical details on 3 individuals, each harboring a private de novo CAMK4 variant.

Overlapping features included DD, ID, behavoral issues, autism and abnormal hyperkinetic movements. Dystonia and chorea in all 3 appeared 3-20 years after initial symptoms.

CAMK4 encodes Calcium/Calmodulin-dependent protein kinase IV, an important mediator of calcium-mediated activity and dynamics, particularly in the brain. It is involved in neuronal transmission, synaptic plasticity, and neuronal gene expression required for brain development and neuronal homeostasis (summary by OMIM based on Zech et al, 2018).

The 473 aa enzyme has a protein kinase domain (aa 46-300) and a C-terminal autoregulatory domain (aa 305-341) the latter comprising an autoinhibitory domain (AID / aa 305-321) and a calmodulin-binding domain (CBD / aa 322-341) [NP_001735.1 / NM_001744.4 - also used below].

Variants in all 3 subjects were identified following trio-WES and were in all cases protein-truncating, mapping to exon 10 or exon 10-intron 10 junction, expected to escape NMD and cause selective abrogation of the autoinhibitory domain (aa 305-321) leading overall to gain-of-function.

Variation databases include pLoF CAMK4 variants albeit in all cases usptream or downstream of this region (pLI of this gene in gnomAD: 0.51). Variants leading to selective abrogation of the autoregulatory domain have not been reported.

Extensive evidence for the GoF effect of the variant has been provided in the first publication. Several previous studies have demonstrated that abrogation of the AID domain leads to consitutive activation (details below).

Mouse models - though corresponding to homozygous loss of function - support a role for CAMKIV in cognitive and motor symptoms. Null mice display tremulous and ataxic movements, deficiencies in balance and sensorimotor performance associated with reduced number of Purkinje neurons (Ribar et al 2000, PMID: 11069976 - not reviewed). Wei et al (2002, PMID: 12006982 - not reviewed) provided evidence for alteration in hippocampal physiology and memory function.

Heterozygous mutations in other genes for calcium/calmodulin-dependent protein kinases (CAMKs) e.g. CAMK2A/CAMK2B (encoding subunits of CAMKII) have been reported in individuals with ID.

---

The proband in the first publication (PMID: 30262571) was a male with DD, ID, behavioral difficulties (ASD, autoaggression, stereotypies) and hyperkinetic movement disorder (myoclonus, chorea, ataxia) with severe generalized dystonia (onset at the age of 13y). Brain MRI demonstrated cerebellar atrophy.

Extensive work-up incl. karyotyping, CMA, DYT-TOR1A, THAP1, GCH1, SCA1/2/3/6/7/8/12/17, Friedreich's ataxia and FMR1 analysis was negative.F

Trio WES identified a dn splice site variant (c.981+1G>A) in the last exon-intron junction. RT-PCR followed by gel electrophoresis and Sanger in fibroblasts from an affected and control subject revealed that the proband had - as predicted by the type/location of the variant - in equal amount 2 cDNA products, a normal as well as a truncated one.

Sequencing of the shortest revealed utilization of a cryptic donor splice site upstream of the mutated donor leading to a 77bp out-of-frame deletion and introduction of a premature stop codon in the last codon (p.Lys303Serfs*28). Western blot in fibroblast cell lines revealed 2 bands corresponding to the normal protein product as well as to the p.Lys303Serfs*28 although expression of the latter was lower than that of the full length protein.

Several previous studies have shown that mutant CAMKIV species that lack the autoinhibitory domain are consitutively active (several Refs provided). Among others Chatila et al (1996, PMID: 8702940) studied an in vitro-engineered truncation mutant (Δ1-317 - truncation at position 317 of the protein) with functionally validated gain-of-function effect.

To prove enhanced activity of the splicing variant, Zech et al assessed phosphorylation of CREB (cyclic AMP-responsive element binding protein), a downstream substrate of CAMKIV. Immunobloting revealed significant increase of CREB phosphorylation in patient fibroblasts compared to controls. Overactivation of CAMKIV signaling was reversed when cells were treated with STO-609 an inhibitor of CAMKK, the ustream activator of CAMKIV.

Overall the authors demonstrated that loss of CAMKIV autoregulatory domain due to this splice variant had a gain-of-function effect.

----

Following trio-WES, Zech et al (2020 - PMID: 33098801) identified another relevant subject within cohort of 764 individuals with dystonia. This 12-y.o. male, harboring a different variant affecting the same donor site (c.981+1G>T), presented DD, ID, dystonia (onset at 3y) and additional movement disorders (myoclonus, ataxia) as well as similar behavior (ASD, autoaggression, stereotypies). [Details in suppl. p20].

----

Finally Zech et al (2020 - PMID: 33211350) reported on a 24-y.o. woman with adolescence onset choreodystonia. Other features included DD, moderate ID, absence seizures in infancy, OCD with anxiety and later diagnosis of ASD. Trio WES revealed a dn stopgain variant (c.940C>T; p.Gln314*).

Individual 2: canonical splice variant, phenotype mostly confined to ASD

Another two de novo variants were identified in the literature by the authors of that paper, one stop-gain (DDD study, PMID 28135719) and one missense (large autism cohort, PMID 25363760).

PMID 33417013 also showed that HIRA knockdown in mice results in neurodevelopmental abnormalities.

Rated Green due to 4 unrelated individuals (albeit 2 in large cohort studies) and a mouse model. NB: HIRA is within the common 22q deletion region.

Added comment: 2 unrelated patients with mild oculocutaneous albinism, moderate bleeding diathesis, platelet aggregation deficit, and a dramatically decreased number of platelet dense granules, all signs compatible with HPS. Identified distinct homozygous variants in the BLOC1S5 gene (patient 1: deletion of exons 3 and 4, patient 2: 1-bp deletion in exon 4). Parental segregation confirmatory in patient 1, quantitative PCR analysis confirmatory in patient 2). Functional tests performed on platelets of one patient displayed an absence of the obligate multisubunit complex BLOC-1, showing that the variant disrupts BLOC1S5 function and impairs BLOC-1 assembly. Expression of the patient-derived BLOC1S5 deletion in nonpigmented murine Bloc1s5-/- melan-mu melanocytes failed to rescue pigmentation, the assembly of a functional BLOC-1 complex, and melanosome cargo trafficking, unlike the wild-type allele. Pathogenic variants in the genes encoding three other BLOC-1 subunits (DTNBP1, BLOC1S3, and BLOC1S6) underlie HPS types 7, 8, and 9 respectively.
