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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 31, 2023The c.335G>A (p.R112H) alteration is located in exon 2 (coding exon 2) of the ISX gene. This alteration results from a G to A substitution at nucleotide position 335, causing the arginine (R) at amino acid position 112 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
