Arina Puzriakova Phenotypes for gene: BSCL2 were changed from Intractable epilepsy and neurological regression; Encephalopathy, progressive, with or without lipodystrophy 615924; Lipodystrophy, congenital generalized, type 2 269700; Neuropathy, distal hereditary motor, type VA 600794; Silver spastic paraplegia syndrome 270685 to Encephalopathy, progressive, with or without lipodystrophy, OMIM:615924
Rebecca Foulger Added comment: Comment on mode of inheritance: As discussed with members of the GMS Neurology Specialist Test Group on the Webex call 22nd November 2019 for Clinical Indication R59 Early onset or syndromic epilepsy: Agreed that MOI should change from 'BOTH monoallelic and biallelic' to 'BIALLELIC': just one monoallelic case so far, which could be a false positive.
Rebecca Foulger Mode of inheritance for gene: BSCL2 was changed from BOTH monoallelic and biallelic, autosomal or pseudoautosomal to BIALLELIC, autosomal or pseudoautosomal

Rebecca Foulger Added comment: Comment on mode of inheritance: PMID:31369919 (Fernandez-Marmiesse et al., 2019) report 2 siblings with profound refractory epilepsy and neurological regression. A de novo Met189Lys variant in BSCL2 was detected that was absent in the parents and unaffected sibling. This is the first evidence of an association between a heterozygous BSCL2 variant and EIEE, and supports an AD+AR Mode of inheritance.
