Genes affected

COMMD1 (HGNC:23024): (copper metabolism domain containing 1) Enables several functions, including phosphatidylinositol-3,4-bisphosphate binding activity; phospholipid binding activity; and protein homodimerization activity. Involved in several processes, including Golgi to plasma membrane transport; negative regulation of protein localization to cell surface; and regulation of cellular protein metabolic process. Acts upstream of or within negative regulation of NF-kappaB transcription factor activity. Located in cytosol; endosome; and nucleoplasm. Part of Cul2-RING ubiquitin ligase complex.

The c.332A>T (p.N111I) alteration is located in exon 2 (coding exon 2) of the COMMD1 gene. This alteration results from a A to T substitution at nucleotide position 332, causing the asparagine (N) at amino acid position 111 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
