Genes affected

SSBP1 (HGNC:11317): (single stranded DNA binding protein 1) SSBP1 is a housekeeping gene involved in mitochondrial biogenesis (Tiranti et al., 1995 [PubMed 7789991]). It is also a subunit of a single-stranded DNA (ssDNA)-binding complex involved in the maintenance of genome stability (Huang et al., 2009) [PubMed 19683501].[supplied by OMIM, Feb 2010]

SSBP1 Gene-Disease associations (from GenCC):

• optic atrophy 13 with retinal and foveal abnormalities

  Inheritance: AD Classification: STRONG, MODERATE Submitted by: ClinGen, Ambry Genetics
