Genes affected

KLHL12 (HGNC:19360): (kelch like family member 12) This gene encodes a member of the KLHL (Kelch-like) family of proteins. This protein has been identified as an autoantigen in the autoimmune disease Sjogren's syndrome and as a potential biomarker in primary biliary cirrhosis. This protein may act as a substrate adaptor of the Cullin-3 ubiquitin ligase complex to promote substrate-specific ubiquitylation. Ubiquitylation by this complex has been shown to regulate the Wnt signaling pathway as well as COPII vesicle coat size. A pseudogene has been identified on chromosome 22. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

The c.1567T>A (p.Y523N) alteration is located in exon 11 (coding exon 10) of the KLHL12 gene. This alteration results from a T to A substitution at nucleotide position 1567, causing the tyrosine (Y) at amino acid position 523 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
