Hereditary neuropathy v1.478 SPTBN4 Arina Puzriakova Phenotypes for gene: SPTBN4 were changed from Neurodevelopmental disorder with hypotonia, neuropathy, and deafness, 617519 to Neurodevelopmental disorder with hypotonia, neuropathy, and deafness, OMIM:617519
Hereditary neuropathy v1.476 MME Arina Puzriakova changed review comment from: Comment on mode of inheritance: Updating from 'biallelic' to 'both mono- and biallelic' inline with MOI on equivalent GMS panel (R78 Hereditary neuropathy or pain disorder).

"Heterozygous variants have been identified in >10 individuals with late-onset CMT2T. However, some variants have been found in control databases and family studies indicate incomplete penetrance, suggesting heterozygous variants only confer susceptibility. Nonetheless, sufficient cases have been reported in literature and both MOIs are listed in OMIM for this phenotype"; to: Comment on mode of inheritance: Updating from 'biallelic' to 'both mono- and biallelic' inline with MOI on equivalent GMS panel (R78 Hereditary neuropathy or pain disorder v3.24).

Hereditary neuropathy v1.403 TFG Arina Puzriakova Added comment: Comment on mode of inheritance: Updated MOI from 'monoallelic' only to 'both mono- and biallelic'

Monoallelic variants are associated with an adult-onset motor and sensory neuropathy (MIM# 604484), a disorder that is relevant to this panel. Biallelic variants cause a HSP (MIM# 615658) which also has been shown to involve peripheral neuropathy in complex cases. Both phenotypes have a sufficient number of unrelated cases (>3) reported to warrant a Green rating (updated publications list).
Hereditary neuropathy v1.399 SORD Sarah Leigh Classified gene: SORD as Green List (high evidence)
Hereditary neuropathy v1.399 SORD Sarah Leigh Added comment: Comment on list classification: Associated with relevant phenotype in OMIM, but not associated with phenotype in Gen2Phen. At least 7 variants reported in unrelated cases. Functional studies showed undetectable SORD protein levels and increased intracellular sorbitol accumulation in patient fibroblasts compared to controls (PMID 32367058).
Hereditary neuropathy v1.399 SORD Sarah Leigh Gene: sord has been classified as Green List (High Evidence).
Hereditary neuropathy v1.398 SORD Sarah Leigh Publications for gene: SORD were set to PMID: 32367058
Hereditary neuropathy v1.397 SORD Sarah Leigh Phenotypes for gene: SORD were changed from CMT2 to Sorbitol dehydrogenase deficiency with peripheral neuropathy OMIM:618912; sorbitol dehydrogenase deficiency with peripheral neuropathy MONDO:0030055
Hereditary neuropathy v1.383 SORD Alexander Rossor gene: SORD was added
gene: SORD was added to Hereditary neuropathy. Sources: Expert list
Mode of inheritance for gene: SORD was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: SORD were set to PMID: 32367058
Phenotypes for gene: SORD were set to CMT2
Penetrance for gene: SORD were set to Complete
Review for gene: SORD was set to GREEN
Added comment: bialleleic variants present in more than 3 unrelated families
Sources: Expert list
Hereditary neuropathy v1.378 SPTBN4 Arina Puzriakova gene: SPTBN4 was added
gene: SPTBN4 was added to Hereditary neuropathy. Sources: Literature
Mode of inheritance for gene: SPTBN4 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: SPTBN4 were set to 28540413; 28940097; 29861105; 31230720; 31857255; 32672909
Phenotypes for gene: SPTBN4 were set to Neurodevelopmental disorder with hypotonia, neuropathy, and deafness, 617519
Review for gene: SPTBN4 was set to GREEN
Added comment: At least 11 individuals from 9 unrelated families with biallelic variants in SPTBN4 reported at present. Motor neuronopathy/axonopathy was reported in 5 unrelated families. A formal evaluation by EMG/NCS was not conducted in the rest but phenotypes did include hypotonia and hyporeflexia which could be suggestive of neuropathy.
