Genes affected

CDHR5 (HGNC:7521): (cadherin related family member 5) This gene is a novel mucin-like gene that is a member of the cadherin superfamily. While encoding nonpolymorphic tandem repeats rich in proline, serine and threonine similar to mucin proteins, the gene also contains sequence encoding calcium-binding motifs found in all cadherins. The role of the hybrid extracellular region and the specific function of this protein have not yet been determined. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jan 2010]

The c.2305G>A (p.G769R) alteration is located in exon 15 (coding exon 15) of the CDHR5 gene. This alteration results from a G to A substitution at nucleotide position 2305, causing the glycine (G) at amino acid position 769 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
