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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 20, 2024The c.1270T>G (p.W424G) alteration is located in exon 10 (coding exon 10) of the SERINC1 gene. This alteration results from a T to G substitution at nucleotide position 1270, causing the tryptophan (W) at amino acid position 424 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
