Genes affected

PLEKHH1 (HGNC:17733): (pleckstrin homology, MyTH4 and FERM domain containing H1) Predicted to be located in cytoskeleton. [provided by Alliance of Genome Resources, Apr 2022]

PLEKHH1 links:

PIGH (HGNC:8964): (phosphatidylinositol glycan anchor biosynthesis class H) This gene encodes an endoplasmic reticulum associated protein that is involved in glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The GPI anchor is a glycolipid found on many blood cells and which serves to anchor proteins to the cell surface. The protein encoded by this gene is a subunit of the GPI N-acetylglucosaminyl (GlcNAc) transferase that transfers GlcNAc to phosphatidylinositol (PI) on the cytoplasmic side of the endoplasmic reticulum.

The c.4031A>G (p.E1344G) alteration is located in exon 29 (coding exon 28) of the PLEKHH1 gene. This alteration results from a A to G substitution at nucleotide position 4031, causing the glutamic acid (E) at amino acid position 1344 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
