Genes affected

NAT8 (HGNC:18069): (N-acetyltransferase 8 (putative)) This gene, isolated using the differential display method to detect tissue-specific genes, is specifically expressed in kidney and liver. The encoded protein shows amino acid sequence similarity to N-acetyltransferases. A similar protein in Xenopus affects cell adhesion and gastrulation movements, and may be localized in the secretory pathway. A highly similar paralog is found in a cluster with this gene.

The c.368G>T (p.G123V) alteration is located in exon 2 (coding exon 1) of the NAT8 gene. This alteration results from a G to T substitution at nucleotide position 368, causing the glycine (G) at amino acid position 123 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
