Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the DHH gene is commonly pathogenic or not.

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: Intercellular signal essential for a variety of patterning events during development. May function as a spermatocyte survival factor in the testes. Essential for testes development.
• Disease: DISEASE: Partial gonadal dysgenesis with minifascicular neuropathy 46,XY (PGD) [MIM:607080]: Characterized by the presence of a testis on one side and a streak or an absent gonad at the other, persistence of Muellerian duct structures, and a variable degree of genital ambiguity. {ECO:0000269|PubMed:11017805}. Note=The disease may be caused by mutations affecting the gene represented in this entry.; DISEASE: 46,XY sex reversal 7 (SRXY7) [MIM:233420]: A disorder of sex development. Affected individuals have a 46,XY karyotype but present as phenotypically normal females. SRXY7 patients have no functional gonads. {ECO:0000269|PubMed:15356051}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
