Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the LHX4 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.

• Disease: DISEASE: Pituitary hormone deficiency, combined, 4 (CPHD4) [MIM:262700]: Combined pituitary hormone deficiency is defined as the impaired production of growth hormone and one or more of the other five anterior pituitary hormones. CPHD4 is characterized by complete or partial deficiencies of growth hormone, thyroid- stimulating hormone, luteinizing hormone, follicle stimulating hormone and adrenocorticotropic hormone. Clinical features include short stature, cerebellar defects, and small sella turcica. {ECO:0000269|PubMed:17527005, ECO:0000269|PubMed:18073311}.
