Retinal disorders v9.17 VWA8 Ida Ertmanska changed review comment from: PMID: 40638000 Chacon-Camacho et al., 2025
Report of a Mexican patient suffering from retinitis pigmentosa. Classical features of retinal dystrophy were identified, including nyctalopia, peripheral visual field loss, as well as vascular attenuation, and bone spicules on fundus examination. Genetic analysis identified a novel pathogenic c.3069C>G (p.Tyr1023Ter) heterozygous VWA8 variant - 2 hets reported in gnomAD v4.1.1.

PMID: 34660594 Umair et al., 2021
Report of a large consanguineous family of Saudi origin with a complex developmental syndrome: global developmental delay, microcephaly, scoliosis, limbs, and cardiovascular malformations. Affected individuals were homozygous for the VWA8: c.947A>G; p.(Asp316Gly) variant - reported in 29 het individuals in gnomAD v4.1.1 (no homozygotes). Seq method: WES + Sanger confirmation in the parents and sibs.
Functional evidence: zebrafish morpholino approach showed delayed development at an early stage, lack of movement, light sensitivity, severe skeletal deformity such as scoliosis, and facial dysmorphism in vwa8-knockdown fish

PMID: 42120427 Kong et al., 2026 - Functional evidence
Authors constructed CRISPR Cas9 gene knockout mice with Vwa8 and identified Vwa8 wild-type, heterozygous (Vwa8+/-), and homozygous (Vwa8-/-) mice. Compared to the wild-type mice, the expression of the Hexokinase 2 (HK2) and Pyruvate kinase muscle (PKM) mitochondrial enzymes was reduced in mitochondria isolated from the retinal tissue of the Vwa8+/- and Vwa8-/- mice.
The Vwa8+/- mice showed partial retina pigmentation compared to the wild-type mice, whereas the Vwa8-/- mice had more significant abnormal pigmentation of the fundus. Electroretinogram (ERG) analysis revealed a significant reduction in b-wave amplitudes under photopic conditions in 10-month-old Vwa8+/- mice when compared to wild-type controls, while it was more severe in Vwa8-/- mice with only minimal electrical responses to light stimulation.; to: PMID: 40638000 Chacon-Camacho et al., 2025

Retinal disorders v9.3 LOXL3 Ida Ertmanska changed review comment from: PMID: 41052910 Sanchez et al., 2026
3 sisters with biallelic LOXL3 variants and Stickler Syndrome. Comp het for c.1735C>T, p.Arg579* and c.956G>A, p.Arg319Gln in LOXL3 - targeted NGS panel. Parents are healthy carriers of one LOXL3 variant each. Shared phenotype: skeletal anomalies in feet and hands, cleft palate, high myopia, bilateral conductive hearing loss (2/3).

PMID: 38957076 Klejnotowska et al., 2024
4yo boy with reduced visual acuity 6/30 in both eyes, bilateral vitreous syneresis, foveal hypoplasia and bilateral high myopia (-8.50D). A skeletal survey showed mild spondylo-epi-metaphyseal dysplasia. Normal hearing. WES revealed a homozygous LOXL3 variant c.1448_1449del, p.(Thr483Argfs*13), inherited through paternal UPiD of chromosome 2.

PMID: 36917121 Jiang et al., 2023
9 unrelated Chinese patients with LOXL3 variants and early-onset extreme high myopia - main and consistent feature across the cohort. No significant skeletal abnormalities, midface development, palate malformation was observed in these nine patients; auditory assessment normal where available. Authors hypothesise that biallelic missense variants result in Stickler syndrome, while truncating variants yield isolated high myopia - this is not very consistent, though.

PMID: 30362103 Chan et al., 2019
Report of a child and his father who had clinical features consistent with Stickler syndrome and found to have a homozygous novel mutation c.1036C>T (p.Arg346Trp) in LOXL3. Clinical features: high myopia, short stature, retinal changes, high-arched palate (son only). No hearing loss.

PMID: 25663169 Alzahrani et al., 2015
Saudi family with AR Stickler syndrome. Parents are second cousins. Index patient: 16yo boy with cleft palate, micro/retrognathia, non-progressive myopia (-10.00 D) with chorioretinal lattice degeneration, mild conductive hearing loss. 8yo sister has similar presentation, with myopia of -13.00 D and normal hearing. Both had normal development. Homozygous LOXL3 c.2027G>T, p.Cys676Phe detected in the sibs (exome seq + autozygosity filtering).

Functional evidence: PMID: 36610533 Liu et al., 2023 - a mouse model of Stickler syndrome was made by inducing a LOXL3 mutation (c.2027G>A, p.Cys676Tyr) using CRISPR/Cas9. The Loxl3 mutant mice exhibited perinatal death, spinal deformity, cleft palate, skeletal dysplasia and progressive visual degeneration.

Clinical features: high myopia, short stature, retinal changes, high-arched palate (son only). No hearing loss. On fundus examination, the father had myopic fundi and peripheral retinal degeneration - seen at age 40 years. The son, age 11 years, had vitreous degeneration/detachment in both eyes.

Mode of inheritance for gene: CFAP20 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: CFAP20 were set to 36329026
Phenotypes for gene: CFAP20 were set to Retinitis pigmentosa (MONDO:0019200)
Review for gene: CFAP20 was set to GREEN
Added comment: Describe 8 individuals from 4 independent families with damaging biallelic variants (homozygous or compound heterozygous) in CFAP20 that segregate with retinal dystrophy. All variants cluster to one side of the protein, with two of the residues directly contacting alpha-tubullin.

Family 1 - consanguineous set of 3 siblings from Sudan, homozygous for CFAP20 c.305G>A; p.Arg102His (they also had a homozygous variant in DYNC1LI2 however CFAP20 was considered the better candidate.
Family 2 - 3 siblings from Spain, 2 with retinal dystrophy, 1 genetically tested and has c.337C>T; p.(Arg113Trp) and c.397delC; p.(Gln133Serfs*5)
Family 3 - single affected family member compound het for c.164+1G>A and c.457A>G; p.(Arg153Gly).
Family 4 - 3 affected siblings with generalised retinopathy and variable neurological deficits with c.164+1G>A and c.257G>A; p.(Tyr86Cys)

For all families, no individuals had signs of polycystic kidney disease; however, not all individuals had kidney imaging. Visual defecit phenotype presented between adolescence and adulthood (17-56 years old).

Used HEK293T cell expression studies to demonstrate a statistically significant decline of mutated CFAP20 protein levels (with the exception of p.Arg102His). To test the specific variants, they used the C.elegans orthologues.

CFAP20 is a ciliopathy candidate. Demonstrate in zebrafish that cfap20 is required for motile cilia function, and in C. elegans, CFAP-20 maintains the structural integrity of non-motile cilia inner junctions, influencing sensory-dependent signalling and development.
