Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the HOXC13 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000017410.3. 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: Transcription factor which plays a role in hair follicle differentiation. Regulates FOXQ1 expression and that of other hair-specific genes (By similarity). {ECO:0000250}.;
Disease: DISEASE: Ectodermal dysplasia 9, hair/nail type (ECTD9) [MIM:614931]: A form of ectodermal dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures such as hair, teeth, nails and sweat glands, with or without any additional clinical sign. Each combination of clinical features represents a different type of ectodermal dysplasia. ECTD9 is characterized by hypotrichosis and nail dystrophy without non-ectodermal or other ectodermal manifestations. Hypotrichosis usually occurs after birth with varying degrees of severity, ranging from mild hair loss to complete atrichia, including the loss of scalp hair, beard, eyebrows, eyelashes, axillary hair, and pubic hair. Nail dystrophy affects all 20 digits by causing short fragile nails or spoon nails (koilonychia). {ECO:0000269|PubMed:23063621, ECO:0000269|PubMed:28297138}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
