Term Description

The presence of the CLRN1 gene mutation c.144T>G (p.N48K, NM_174878.2) is associated with Usher syndrome type III. Among Ashkenazi Jewish individuals, the carrier frequency is 1/120 (0.8%) and detection rate is about 98%. If negative, the patient's carrier risk is reduced from 1/120 to less than 1/5951 (0.02%).

Part Description

LP193289-8   CLRN1 gene.c.144T>G
The CLRN1 (clarin 1) gene [HGNC Gene ID: 12605] is located on chromosome 3q25. This gene encodes a protein that contains a cytosolic N-terminus, multiple helical transmembrane domains, and an endoplasmic reticulum membrane retention signal, TKGH, in the C-terminus. The encoded protein may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIIa. Multiple transcript variants encoding distinct isoforms have been identified for this gene.
