Genes affected

ARMS2 (HGNC:32685): (age-related maculopathy susceptibility 2) This gene encodes a small secreted protein specific to primates. This protein is a component of the choroidal extracellular matrix of the eye. Mutations in this gene are associated with age-related macular degeneration. [provided by RefSeq, Sep 2017]

Ambry Genetics

Jun 06, 2023

The c.232C>G (p.P78A) alteration is located in exon 1 (coding exon 1) of the ARMS2 gene. This alteration results from a C to G substitution at nucleotide position 232, causing the proline (P) at amino acid position 78 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
