Genes affected

ISX (HGNC:28084): (intestine specific homeobox) Homeobox genes encode DNA-binding proteins, many of which are thought to be involved in early embryonic development. Homeobox genes encode a DNA-binding domain of 60 to 63 amino acids referred to as the homeodomain. This gene is a member of the RAXLX homeobox gene family. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 12, 2024

The c.115A>G (p.R39G) alteration is located in exon 1 (coding exon 1) of the ISX gene. This alteration results from a A to G substitution at nucleotide position 115, causing the arginine (R) at amino acid position 39 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
