Expansion of the genetic landscape of ERLIN2-related disorders.

ABSTRACT: ERLIN2-related disorders are rare conditions of the motor system and clinical details are limited to a small number of prior descriptions. We here presented clinical and genetic details in five individuals (four different families) where three subjects carried a common homozygous p.Asn292ArgfsX26, associated also with sensorineural hearing loss in one child. One further subject had a de novo p.Gln63Lys and one harbors the homozygous p.Val136Gly because of maternal isodisomy of chromosome 8. Overall, we expanded the clinical and genetic spectrum of ERLIN2-related disorders and we reiterate that autosomal-dominant transmission is a potential mode of inheritance. Future research will elucidate disease mechanisms.
