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]

The c.443C>T (p.A148V) alteration is located in exon 3 (coding exon 3) of the ISX gene. This alteration results from a C to T substitution at nucleotide position 443, causing the alanine (A) at amino acid position 148 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
