Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TMEM132E gene is commonly pathogenic or not. These statistics are base on transcript: NM_001304438.2. 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: Required for normal inner ear hair cell function and hearing. {ECO:0000269|PubMed:25331638}.
• Disease: DISEASE: Note=TMEM132E is located in a region involved in a heterozygous deletion of approximately 4.7 Mb; this deletion, involving the NF1 gene and contiguous genes lying in its flanking regions, is observed in a patient 17q11.2 microdeletion syndrome, a syndrome characterized by variable facial dysmorphism, mental retardation, developmental delay, and an excessive number of neurofibromas. {ECO:0000269|PubMed:14569139}.; DISEASE: Note=Several lines of evidence link the Gln-420 variant with autosomal recessive non-syndromic hearing loss. This variant has been reported in 2 siblings with prelingual, bilateral, severe to profound sensorineural hearing loss from a Chinese family of consanguineous marriage and was not found in 500 ethnically matched healthy controls. In mouse, TMEM132E is expressed in cochlea hair cells. In addition, knockdown in zebrafish affects the mechanotransduction of hair cells, a phenotype that can be rescued by wild-type human TMEM132E, but not by the Gln-420 variant. {ECO:0000269|PubMed:25331638}.
