Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SPECC1L gene is commonly pathogenic or not. These statistics are base on transcript: NM_000015330.6. 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 cytokinesis and spindle organization. May play a role in actin cytoskeleton organization and microtubule stabilization and hence required for proper cell adhesion and migration. {ECO:0000269|PubMed:21703590}.
• Disease: DISEASE: Facial clefting, oblique, 1 (OBLFC1) [MIM:600251]: A rare form of facial clefting. A facial cleft is any of the fissures between the embryonic prominences that normally unite to form the face. {ECO:0000269|PubMed:21703590}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Opitz GBBB syndrome 2 (GBBB2) [MIM:145410]: A form of Opitz GBBB syndrome, a congenital midline malformation syndrome characterized by hypertelorism, genital-urinary defects such as hypospadias in males and splayed labia in females, cleft lip/palate, laryngotracheoesophageal abnormalities, imperforate anus, developmental delay and congenital heart defects. {ECO:0000269|PubMed:25412741}. Note=The disease is caused by mutations affecting the gene represented in this entry.
