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.3994C>G (p.P1332A) alteration is located in exon 29 (coding exon 28) of the PLEKHH1 gene. This alteration results from a C to G substitution at nucleotide position 3994, causing the proline (P) at amino acid position 1332 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
