Hereditary Neuropathy v1.19 BAG3 Chirag Patel edited their review of gene: BAG3: Added comment: PMID: 37907725
7 individuals from the one family with distal motor neuronopathy (mean age of onset ~46 years). They presented with slowly progressive and symmetric distal weakness and atrophy of lower limb muscles, absent Achilles reflexes, and neurogenic changes on muscle biopsies. There were no sensory abnormalities or signs of myofibrillar myopathy. WES with segregation analysis identified a novel heterozygous truncating variant in the gene BAG3 in all affected family members [c.1513_1514insGGAC (p.Val505GlyfsTer6)]. There was autosomal dominant inheritance with incomplete penetrance in women. Western blot analysis of muscle tissue from 2 individuals showed presence of a truncated BAG3 protein. Functional studies of the variant were not performed.

PMID: 31853710
2 individuals from a Chinese family with adult-onset and moderate CMT. Nerve conduction velocity studies and sural nerve biopsy revealed an axonal sensorimotor neuropathy. MRI showed fatty infiltration more severe in the soleus and deep posterior compartment muscles. WES identified a missense variant (p.Pro209Ser) in BAG3 gene, which co-segregated with the CMT disease in the family. Functional studies of the variant were not performed.

PMID: 30145633
1 individual with axonal sensory-motor polyneuropathy, myopathy (and raised CK levels), rigid spine syndrome, and respiratory dysfunction (but no cardiomyopathy). MRI showed bilateral symmetric fatty atrophy of muscles at the lower limb and paraspinal muscles. WES identified the same missense variant (p.Pro209Ser) in BAG3 gene, and it was de novo in the individual. Functional studies of the variant were not performed.

PMID: 28754666
9 affected individuals from 2 large multigenerational families with CMT phenotype, but no evidence of a myopathy.

Null mouse and patient derived white adipose tissue showed enrichment of arachidonic acid-containing membrane phospholipids and a strong decrease in PPARγ. CRISPR–Cas9-mediated PLAAT3 inactivation in human adipose stem cells induced insulin resistance, altered adipocyte differentiation with decreased lipid droplet formation and reduced the expression of adipogenic and mature adipocyte markers, including PPARγ.

Neuropathy like phenotypes are only present in individuals with monoallelic variants in ATAD3A

PMID: 27640307
5 affected individuals from 5 unrelated families with the recurrent heterozygous de novo mutation (p.Arg528Trp) with all individuals presenting with symptoms of peripheral neuropathy.

Fly functional study conducted that showed a dramatic reduction in survival in the presence of the mutant protein suggesting it is highly toxic.
The loss of function phenotype assiociated with bor was assessed by performing transmission electron microscopy (TEM) on the first larvae prior to their death and identified a dramatic decrease in mitochondrial content indicating a similarity in phenotype for both LoF and GoF.Therefore the mode of pathogenicity is suggestive of dominant negative.

Added comment: [Please note that HGNC Approved Gene Symbol for this gene is NARS1] Manole et al (2020 - PMID: 32738225) provide evidence that both biallelic and monoallelic (de novo) pathogenic NARS1 variants cause a neurodevelopmental disorder. In total 32 individuals from 21 families are reported, with biallelic variants identified in individuals from 13 families and de novo in 8 families. Similar features were reported for AR/AD occurrences of the disorder and included microcephaly (90% - most often primary), epilepsy (23/32 or 74% - variable semiology incl. partial/myoclonic/generalized tonic-clonic seizures), DD and ID (as a universal feature), abnormal tone in several (hypotonia/spasticity), ataxia, demyelinating peripheral neuropathy (in 3 or more for each inheritance mode - or a total of 25%). Some individuals had dysmorphic features. NARS1 encodes an aminoacyl-tRNA synthetase (ARS) [asparaginyl-tRNA synthetase 1]. Aminoacyl-tRNA synthetases constitute a family of enzymes catalyzing attachment of amino-acids to their cognate tRNAs. As the authors comment, mutations in genes encoding several other ARSs result in neurological disorders ranging from peripheral neuropathy to severe multi-systemic NDD. Dominant, recessive or both modes for inheritance for mutations in the same gene (e.g. AARS1, YARS1, MARS1, etc) have been reported. Some variants were recurrent, e.g. the c.1600C>T / p.Arg534* which occurred in 6 families as a de novo event or c.1633C>T p.Arg545Cys (homozygous in 6 families). 3 different variants were reported to have occured de novo (c.965G>T - p.Arg322Leu, c.1525G>A - p.Gly509Ser, p.Arg534*) with several other variants identified in hmz/compound htz individuals. A single SNV (c.1067A>C - p.Asp356Ala) was suggested to be acting as modifier and pathogenic only when in trans with a severe variant. [NM_004539.4 used as RefSeq for all]. The authors provide several lines of evidence for a partial loss-of-function effect (e.g. reduction in mRNA expression, enzyme levels and activity in fibroblasts or iNPCs) underlying pathogenicity of the variants identified in individuals with biallelic variants. A gain-of-function (dominant-negative) effect is proposed for de novo variants (such effect also demonstrated for the p.Arg534* in a zebrafish model).

Added comment: Missense mutations identified in two families. First family, proband presented with ascending and descending aortic aneurysms, bilateral lower leg and foot sensorimotor peripheral neuropathy, arthropathy, and increased skin elasticity. Variant segregated with disease in the affected proband, mother, and son. Second family, father and three affected children showed amyotrophy and weakness of the distal lower limbs, dating back to early childhood. Some functional studies performed in patient fibroblasts and zebrafish, however these were not conclusive as the two missense mutations are at different locations within the protein.

Hereditary Neuropathy v0.64 MCM3AP Zornitza Stark edited their review of gene: MCM3AP: Added comment: PMID: 32202298 - Woldegebriel et al 2020 - report a further two families, one in the Netherlands and one in Estonia, with probands with compound heterozygous variants in MCM3AP and a peripheral neuropathy with or without impaired intellectual development (MIM 618124) phenotype. The child from the Netherlands presented with severe hypotonia and intellectual disability. The two siblings from the Estonian family had severe generalized epilepsy and mild spastic diplegia. Functional studies using skin fibroblasts from these and other affected patients showed that disease variants result in depletion of GANP (encoded by MCM3AP) except when they alter critical residues in the Sac3 mRNA binding domain. GANP depletion was associated with more severe phenotypes compared with the Sac3 variants.; Changed publications: 24123876, 28633435, 28969388, 29982295, 32202298

Added comment: Multiple families reported. Clinical presentation is highly variable. Complex progressive neurologic disorder characterised mainly by early-onset optic atrophy resulting in progressive visual loss and peripheral axonal sensorimotor neuropathy with highly variable age at onset and severity. Affected individuals also have cerebellar or pontocerebellar atrophy on brain imaging, and they may show abnormal movements, such as ataxia, dysmetria, and myoclonus. The most severely affected patients are hypotonic at birth and die in infancy.
