Genes affected

ZHX1 (HGNC:12871): (zinc fingers and homeoboxes 1) The members of the zinc fingers and homeoboxes gene family are nuclear homodimeric transcriptional repressors that interact with the A subunit of nuclear factor-Y (NF-YA) and contain two C2H2-type zinc fingers and five homeobox DNA-binding domains. This gene encodes member 1 of this gene family. In addition to forming homodimers, this protein heterodimerizes with members 2 and 3 of the zinc fingers and homeoboxes family. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream chromosome 8 open reading frame 76 (C8orf76) gene.

ZHX1 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.

The c.1850C>T (p.T617I) alteration is located in exon 3 (coding exon 1) of the ZHX1 gene. This alteration results from a C to T substitution at nucleotide position 1850, causing the threonine (T) at amino acid position 617 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
