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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 31, 2024The c.100A>T (p.I34F) alteration is located in exon 1 (coding exon 1) of the ARMS2 gene. This alteration results from a A to T substitution at nucleotide position 100, causing the isoleucine (I) at amino acid position 34 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
