Added comment: PMID: 40430072 2 siblings with psychosis and schizophrenia, homozygous for Cys441Tyr. Some modelling suggested a deleterious affect but no functional studies performed.

PMID: 41024252 8 patients from 7 families with joint hyperlaxity, with or without short stature and renal disease. 6 families were homozygous for p.(Cys539Trpfs*64) while the other two were homozygous for p.(Lys681*). Paper described both as founder variants but they are rare/absent in gnomad.

Joint hyperlaxity (7), chronic kidney disease/FSGS (2) small echogenic kidneys (3), acute kidney injury (1), dysmorphic features (6), short stature (6), speech delay (3).

One patient also had epilepsy, developmental delay and spasticity however c.728+1G>A in WDR45 explained this part of her phenotype. Other patients also had more severe outlying symptoms with no other explanation mentioned: 1 with developmental delay, hearing loss, brain malformations, skeletal abnormalities, and another a 3 year old who passed away following a complex medical course including blue sclera, proximal tibial fracture, severe respiratory distress due to a chest infection, and acute kidney injury.

Amber given the variable phenotype findings of the reported patients and only 2 homozygous variants identified so far

Added comment: PMID: 39609633 - 7 cases from 5 unrelated families with biallelic variants and a complex neurodevelopmental syndrome. The most frequent phenotypes were corpus callosum dysgenesis (7/7), microcephaly (7/7), mild to severe intellectual disability (7/7), epilepsy (7/7). Additionally, mouse models recapitulate the human phenotype. Loss of function is the mechanism of disease. Heterozygous parents had no phenotype.

Limited evidence for mono allelic association with congenital heart defects
PMID: 35474353 - rare assumed de novo heterozygous variant (NM_014969.5:c.2056G>A p.(Val686Ile) - 10 hets in gnomAD v4.1) detected in a case with heterotaxy including AVCD, vena azygos continuation, artery lusoria, truncus bicaroticus and polysplenia. Screening of exams for 2,019 individuals with situs inversus totalis, heterotaxy, or isolated CHD detected 2 additional individuals with monoallelic rare missense variants. No functional assays or other supporting evidence. All variants are VUS

Review for gene: WDR44 was set to GREEN
Added comment: 11 male patients with 6 missense and 1 nonsense variant in WDR44 displaying a wide range of cognitive impairment and variable congenital anomalies associated with primary cilium dysfunction. 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.
