Genes affected

PLEKHA1 (HGNC:14335): (pleckstrin homology domain containing A1) This gene encodes a pleckstrin homology domain-containing adapter protein. The encoded protein is localized to the plasma membrane where it specifically binds phosphatidylinositol 3,4-bisphosphate. This protein may be involved in the formation of signaling complexes in the plasma membrane. Polymorphisms in this gene are associated with age-related macular degeneration. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 5.[provided by RefSeq, Sep 2010]

The c.811G>T (p.A271S) alteration is located in exon 11 (coding exon 10) of the PLEKHA1 gene. This alteration results from a G to T substitution at nucleotide position 811, causing the alanine (A) at amino acid position 271 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
