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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=5.505092E-7).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.848 is higher than 0.05.
