TVP23C-CDRT4

protein-coding

TVP23C-CDRT4 readthrough

Gene summary

This locus represents naturally occurring readthrough transcription between the neighboring TVP23C (trans-golgi network vesicle protein 23 homolog) and CDRT4 (CMT1A duplicated region transcript 4) genes on chromosome 17. Alternative splicing results in multiple transcript variants, one of which encodes a protein that shares sequence identity with the upstream gene product, but its C-terminus is distinct due to frameshifts relative to the downstream gene.

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript . Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
