Genes affected

TINAGL1 (HGNC:19168): (tubulointerstitial nephritis antigen like 1) The protein encoded by this gene is similar in sequence to tubulointerstitial nephritis antigen, a secreted glycoprotein that is recognized by antibodies in some types of immune-related tubulointerstitial nephritis. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2011]

Collection Method: clinical testing

The c.83G>A (p.R28H) alteration is located in exon 2 (coding exon 1) of the TINAGL1 gene. This alteration results from a G to A substitution at nucleotide position 83, causing the arginine (R) at amino acid position 28 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
