Genes affected

CDX4 (HGNC:1808): (caudal type homeobox 4) This gene encodes a member of a small subfamily of homeobox containing transcription factors. The encoded protein may regulate homeobox gene expression during anteroposterior patterning and hematopoiesis. [provided by RefSeq, Aug 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32874575).

The c.481C>G (p.R161G) alteration is located in exon 1 (coding exon 1) of the CDX4 gene. This alteration results from a C to G substitution at nucleotide position 481, causing the arginine (R) at amino acid position 161 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
