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.1475C>T (p.S492L) 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 1475, causing the serine (S) at amino acid position 492 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
