Charcot-Marie-Tooth disease type 2 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 06, 2023 | This sequence change creates a premature translational stop signal (p.Glu189*) in the BSCL2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BSCL2 are known to be pathogenic (PMID: 11479539, 23564749). This variant is present in population databases (rs137852975, gnomAD 0.04%). This premature translational stop signal has been observed in individual(s) with Berardinelli-Seip congenital lipodystrophy (PMID: 18057387, 19041432, 19762912, 24778225, 27612026). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as p.Glu253*. ClinVar contains an entry for this variant (Variation ID: 4546). For these reasons, this variant has been classified as Pathogenic. - |
