Missense variant in AQP4 seen homozygous in 2 siblings and het in the parents. Patients had macrocephaly, developmental delay, hypotonia, epilepsy, and cognitive deficit. Western blots on generated MDCK cell lines showed no detectable expression of AQP4 protein from the cells with the patients variant. Immunofluorescence also showed no membrane expression. Overexpression studies in HEK293T cells showed WT was seen as mainly monomers or dimers where as variant protein formed large aggregates- likely due to the saturation of protein degradation pathways because of the overexpression.

All 3 were de novo and unaffected siblings did not have the variants. All patients have macrocephaly, delayed motor development, seizures, all had varying degrees of cognitive deficits. 2 also had spasticity, ataxia and dystonia. MRI showed MLC, abnormal and swollen cerebral white matter. Patient cell lines showed reduced regulatory volume decrease, and western blot showed a strong increase in GRPC5B levels in patient lymphoblasts. Together, these findings indicate disturbed volume regulation in lymphoblasts from patients with GPRC5B variants, potentially due to increased GPRC5B levels. Transfected cells caused increased volume-regulated anion channel activity. Sources: Literature |

All unaffected siblings were heterozygous. Patient 1 (missense) presented with Coombs-positive hemolytic anemia, hepatosplenomegaly, Cranial MRI showed bilateral effusions, sulcal hyperintensity, and lateral parietal subcortical acute focal ischemic lesions. Patient 2 (nonsense) presented with recurrent purulent otitis media and a chronic wet cough, persistent jaundice, recurrent chest and ear infections, lingular consolidation, mild bronchiectasis, bibasilar bronchial wall thickening, right peribronchial consolidation, right lower lobe bronchiectasis, bilateral axillary lymphadenopathy, and splenomegaly. Patient 3 (nonsense) presented with suffered headaches, abdomen pain, mouth ulcers, and recurrent infections - Functional studies show patient 1 (missense) with reduced protein expression on western blot, and patient 2/3 (nonsense) with no protein expression. T cells of Pt 1 were similar to mouse K/O model (elevated basal LC3-II, reduced autophagic flux). gnomAD: 0 homozygous PTCs, but a very common canonical splice which is present in the non-canonical transcript Sources: Literature |

This gene encodes part of the subcortical maternal complex (SCMC). Other genes in this group act as 'maternal effect' genes and are associated with early embryonic arrest, recurrent hydatiform mole and MLID in offspring. As is the case for other genes encoding components of the SCMC, the pathogenicity of variants can be difficult to establish as reproductive outcomes are not recorded in genomic databases and variants may be listed in population databases as they are not classed as pathogenic in males or women with no reproductive history. Functional studies of genes encoding components of the SCMC are limited as their expression is restricted to the oocyte and early embryo. Sources: Literature |

| Mendeliome v0.4531 | IBA57 |
Zornitza Stark changed review comment from: More than 15 families reported with bi-allelic variants in this gene and a severe neurodegenerative disorder characterised by loss of previously acquired developmental milestones in the first months or years of life. Some affected individuals have normal development in early infancy before the onset of symptoms, whereas others show delays from birth. Features included loss of motor function, spasticity, pyramidal signs, loss of speech, and cognitive impairment. The disease course is highly variable: some individuals die of respiratory failure early in childhood, whereas some survive but may be bedridden with a feeding tube. Less commonly, some individuals may survive and have a stable course with motor deficits and mild or even absent cognitive impairment, although there may be fluctuating symptoms, often in response to infection. Other variable features include visual problems and seizures. Brain imaging shows diffuse leukodystrophy in the subcortical region, brainstem, cerebellum, and spinal cord. Laboratory studies tend to show increased lactate and CSF glycine, and decreased activity of mitochondrial complexes I and II, although these findings are also variable.; to: MMDS3: More than 15 families reported with bi-allelic variants in this gene and a severe neurodegenerative disorder characterised by loss of previously acquired developmental milestones in the first months or years of life.
