Genes affected

HOXC11 (HGNC:5123): (homeobox C11) This gene belongs to the homeobox family of genes. The homeobox genes encode a highly conserved family of transcription factors that play an important role in morphogenesis in all multicellular organisms. Mammals possess four similar homeobox gene clusters, HOXA, HOXB, HOXC and HOXD, which are located on different chromosomes and consist of 9 to 11 genes arranged in tandem. This gene is one of several homeobox HOXC genes located in a cluster on chromosome 12. The product of this gene binds to a promoter element of the lactase-phlorizin hydrolase. It also may play a role in early intestinal development. An alternatively spliced variant encoding a shorter isoform has been described but its full-length nature has not been determined.

HOXC11 links:

HOTAIR (HGNC:33510): (HOX transcript antisense RNA) This gene is located within the Homeobox C (HOXC) gene cluster on chromosome 12 and is co-expressed with the HOXC genes. It functions through an RNA product, which binds lysine specific demethylase 1 (LSD1) and Polycomb repressive complex 2 (PRC2), and serves as a scaffold to assemble these regulators at the HOXD gene cluster, thereby promoting epigenetic repression of HOXD. This gene is highly expressed in multiple tumors. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Feb 2019]

The c.404C>G (p.A135G) alteration is located in exon 1 (coding exon 1) of the HOXC11 gene. This alteration results from a C to G substitution at nucleotide position 404, causing the alanine (A) at amino acid position 135 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
