PMID:25466870 - Five individuals from two different families with demyelinating sensorimotor peripheral neuropathy and identified with homozygous DNAJC3 variants (family 1: c.580C>T (p.Arg194Ter); family 2: 72kb del (exons 6-12)).
PMID:28940199 - Cousin of family 1 from PMID:2546687 with the same variant and presented with demyelinating sensorimotor peripheral neuropathy.
PMID:32738013 - Two unrelated cases with homozygous splice site variants (case 1: c.393+2T>G; case 2: c.393+2T>C) in DNAJC3 and were reported with sensorimotor demyelinating and axonal polyneuropathy.
PMID:33486469 - Two unrelated patients identified with compound heterozygous (patient 1: p.Met1Val & p.Arg346Ter) or homozygous (p.Arg393Ter) variants, of which patient 1 had demyelinating peripheral sensorimotor neuropathy.
PMID:34654017 - One of two siblings identified with homozygous DNAJC3 variant (c.367_1370delAGAA; p.Lys456SerfsTer85) presented with demyelinating neuropathy.Created: 28 Jul 2023, 3:11 p.m. | Last Modified: 28 Jul 2023, 3:27 p.m.

The Neurology Specialist Test Group agreed that this gene was recommended for the WGS panel based on a broader phenotype view to include conditions where neuropathy is part of a more complex phenotype or where there is overlap with another neurological presentation eg. HSP. This panel includes conditions where neuropathy is part of a more complex phenotype or where there is overlap with another neurological presentation. This panel as going to be used for R78, but subsequently during the follow up call on 21st June with the Test Group it was agreed that it was more clinically relevant for R78 to be restricted to genes that are associated with isolated neuropathy and as a result a new panel was created https://panelapp.genomicsengland.co.uk/panels/846/ for this purpose.Created: 7 Dec 2019, 6:08 p.m. | Last Modified: 7 Dec 2019, 6:08 p.m.
