Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the CPAMD8 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000015692.5. 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.

• Disease: DISEASE: Anterior segment dysgenesis 8 (ASGD8) [MIM:617319]: A form of anterior segment dysgenesis, a group of defects affecting anterior structures of the eye including cornea, iris, lens, trabecular meshwork, and Schlemm canal. Anterior segment dysgeneses result from abnormal migration or differentiation of the neural crest derived mesenchymal cells that give rise to components of the anterior chamber during eye development. Different anterior segment anomalies may exist alone or in combination, including iris hypoplasia, enlarged or reduced corneal diameter, corneal vascularization and opacity, posterior embryotoxon, corectopia, polycoria, abnormal iridocorneal angle, ectopia lentis, and anterior synechiae between the iris and posterior corneal surface. Clinical conditions falling within the phenotypic spectrum of anterior segment dysgeneses include aniridia, Axenfeld anomaly, Reiger anomaly/syndrome, Peters anomaly, and iridogoniodysgenesis. ASGD8 patients predominantly manifest iris and lens abnormalities, in the absence of retinal abnormalities or extra-ocular features. ASGD8 transmission pattern is consistent with autosomal recessive inheritance. {ECO:0000269|PubMed:27839872}. Note=The disease is caused by mutations affecting the gene represented in this entry.
