Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the CABP4 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000145200.5. Only rare variants are included in the table.

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: Involved in normal synaptic function through regulation of Ca(2+) influx and neurotransmitter release in photoreceptor synaptic terminals and in auditory transmission. Modulator of CACNA1D and CACNA1F, suppressing the calcium-dependent inactivation and shifting the activation range to more hyperpolarized voltages (By similarity). {ECO:0000250}.
• Disease: DISEASE: Cone-rod synaptic disorder, congenital non-progressive (CRSD) [MIM:610427]: A non-progressive retinal disorder characterized by stable low vision, nystagmus, photophobia, a normal or near-normal fundus appearance, and no night blindness. {ECO:0000269|PubMed:16960802}. Note=The disease is caused by mutations affecting the gene represented in this entry.
