C8orf76 links:

ZHX1-C8orf76 (HGNC:42975): (ZHX1-C8orf76 readthrough) This locus represents naturally occurring read-through transcription between the neighboring zinc fingers and homeoboxes 1 (ZHX1) and chromosome 8 open reading frame 76 (C8orf76) genes. The read-through transcript encodes a protein that shares sequence identity with the downstream gene, but it has a distinct N-terminus encoded by exon structure from the upstream gene.

Ambry Genetics

Jul 09, 2021

The c.22T>G (p.F8V) alteration is located in exon 1 (coding exon 1) of the C8orf76 gene. This alteration results from a T to G substitution at nucleotide position 22, causing the phenylalanine (F) at amino acid position 8 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
