Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PCDH15 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Calcium-dependent cell-adhesion protein. Essential for maintenance of normal retinal and cochlear function.
• Disease: DISEASE: Usher syndrome 1F (USH1F) [MIM:602083]: USH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH1 is characterized by profound congenital sensorineural deafness, absent vestibular function and prepubertal onset of progressive retinitis pigmentosa leading to blindness. {ECO:0000269|PubMed:15660226, ECO:0000269|PubMed:22815625}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Usher syndrome 1D/F (USH1DF) [MIM:601067]: USH1DF patients are heterozygous for mutations in CDH23 and PCDH15, indicating a digenic inheritance pattern. {ECO:0000269|PubMed:15537665, ECO:0000269|PubMed:18719945}. Note=The disease is caused by mutations affecting distinct genetic loci, including the gene represented in this entry.; DISEASE: Deafness, autosomal recessive, 23 (DFNB23) [MIM:609533]: A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. {ECO:0000269|PubMed:14570705, ECO:0000269|PubMed:18719945, ECO:0000269|PubMed:28281779}.
