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.

Collection Method: clinical testing

The c.530C>T (p.T177I) alteration is located in exon 2 (coding exon 1) of the NAT8 gene. This alteration results from a C to T substitution at nucleotide position 530, causing the threonine (T) at amino acid position 177 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
