Comment on list classification: Following discussion with Helen Brittain (Genomics England Clinical Team) it has been agreed to add this gene as Amber, awaiting review by the GMS specialist group (added 'for-review' tag).

Although neuropathy is reported in at least 5 unrelated cases with biallelic SPTBN4 variants, the phenotype relevance requires review due to the more limited scope of this panel.
Created: 10 Nov 2020, 5:40 p.m. | Last Modified: 10 Nov 2020, 5:40 p.m.
Panel Version: 1.17
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.
