Genes affected

EFR3A (HGNC:28970): (EFR3 homolog A) The protein encoded by this gene is part of a complex that plays a role in maintaining an active pool of phosphatidylinositol 4-kinase (PI4K) at the plasma membrane. This protein is thought to be a peripheral membrane protein that associates with the plasma membrane through palmitoylation. Studies indicate that this gene product plays a role in controlling G protein-coupled receptor (GPCR) activity by affecting receptor phosphorylation. Whole exome sequencing studies have implicated mutations in this gene with autism spectrum disorders. [provided by RefSeq, Apr 2016]

Sep 14, 2022

The c.38G>A (p.R13H) alteration is located in exon 2 (coding exon 2) of the EFR3A gene. This alteration results from a G to A substitution at nucleotide position 38, causing the arginine (R) at amino acid position 13 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
