Genes affected

SERINC1 (HGNC:13464): (serine incorporator 1) Predicted to enable protein-macromolecule adaptor activity. Predicted to be involved in several processes, including phosphatidylserine metabolic process; positive regulation of CDP-diacylglycerol-serine O-phosphatidyltransferase activity; and positive regulation of serine C-palmitoyltransferase activity. Predicted to be located in endoplasmic reticulum membrane and plasma membrane. Predicted to be active in membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.330A>C (p.K110N) alteration is located in exon 3 (coding exon 3) of the SERINC1 gene. This alteration results from a A to C substitution at nucleotide position 330, causing the lysine (K) at amino acid position 110 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
