Genes affected

CHRDL1 (HGNC:29861): (chordin like 1) This gene encodes an antagonist of bone morphogenetic protein 4. The encoded protein may play a role in topographic retinotectal projection and in the regulation of retinal angiogenesis in response to hypoxia. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jan 2009]

Feb 21, 2024

The c.1270G>A (p.G424R) alteration is located in exon 12 (coding exon 11) of the CHRDL1 gene. This alteration results from a G to A substitution at nucleotide position 1270, causing the glycine (G) at amino acid position 424 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
