Genes affected

IRX5 (HGNC:14361): (iroquois homeobox 5) This gene encodes a member of the iroquois homeobox gene family, which are involved in several embryonic developmental processes. Knockout mice lacking this gene show that it is required for retinal cone bipolar cell differentiation, and that it negatively regulates potassium channel gene expression in the heart to ensure coordinated cardiac repolarization. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

CRNDE (HGNC:37078): (colorectal neoplasia differentially expressed) This gene is transcribed into multiple transcript variants, some of which may function as non-coding RNAs. One of the transcript variants encodes a putative short protein that is localized to the nucleus (PMID:25978564). Expression of this locus is increased in proliferating tissues, including certain tumors such as colorectal adenomas and adenocarcinomas. Transcription from this gene is negatively regulated by insulin and insulin-like growth factors, and may regulate the expression of genes involved in metabolism. [provided by RefSeq, May 2015]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
