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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2022The c.1043C>T (p.T348M) alteration is located in exon 10 (coding exon 9) of the CHRDL1 gene. This alteration results from a C to T substitution at nucleotide position 1043, causing the threonine (T) at amino acid position 348 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
