Genes affected

CNPY1 (HGNC:27786): (canopy FGF signaling regulator 1) Cnpy1 is expressed in the midbrain-hindbrain (MHB) boundary in zebrafish, binds FGFR1 (MIM 136350), and plays a role in FGF signaling (Hirate and Okamoto, 2006 [PubMed 16488878]).[supplied by OMIM, Dec 2008]

Ambry Genetics

May 06, 2024

The c.124T>C (p.Y42H) alteration is located in exon 2 (coding exon 1) of the CNPY1 gene. This alteration results from a T to C substitution at nucleotide position 124, causing the tyrosine (Y) at amino acid position 42 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
