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]

The c.686C>T (p.A229V) alteration is located in exon 8 (coding exon 7) of the CHRDL1 gene. This alteration results from a C to T substitution at nucleotide position 686, causing the alanine (A) at amino acid position 229 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
