Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ANOS1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000000216.4. 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: Has a dual branch-promoting and guidance activity, which may play an important role in the patterning of mitral and tufted cell collaterals to the olfactory cortex (By similarity). Chemoattractant for fetal olfactory epithelial cells. {ECO:0000250, ECO:0000269|PubMed:19696444}.;
Disease
DISEASE: Hypogonadotropic hypogonadism 1 with or without anosmia (HH1) [MIM:308700]: A disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic- pituitary axis. In some cases, it is associated with non- reproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss. Anosmia or hyposmia is related to the absence or hypoplasia of the olfactory bulbs and tracts. Hypogonadism is due to deficiency in gonadotropin-releasing hormone and probably results from a failure of embryonic migration of gonadotropin-releasing hormone-synthesizing neurons. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism is referred to as Kallmann syndrome, whereas in the presence of a normal sense of smell, it has been termed normosmic idiopathic hypogonadotropic hypogonadism (nIHH). {ECO:0000269|PubMed:11297579, ECO:0000269|PubMed:15001591, ECO:0000269|PubMed:15471890, ECO:0000269|PubMed:15605412, ECO:0000269|PubMed:17054399, ECO:0000269|PubMed:17213338, ECO:0000269|PubMed:17223984, ECO:0000269|PubMed:19696444, ECO:0000269|PubMed:20530987, ECO:0000269|PubMed:21168128, ECO:0000269|PubMed:23643382, ECO:0000269|PubMed:25077900, ECO:0000269|PubMed:8504298, ECO:0000269|PubMed:8989261, ECO:0000269|PubMed:9589672}. Note=The disease is caused by mutations affecting distinct genetic loci, including the gene represented in this entry. The genetics of hypogonadotropic hypogonadism involves various modes of transmission. Oligogenic inheritance has been reported in some patients carrying mutations in ANOS1 as well as in other HH-associated genes including FGFR1 and TACR3 (PubMed:23643382). {ECO:0000269|PubMed:23643382}.;
