Genes affected

TAS2R4 (HGNC:14911): (taste 2 receptor member 4) This gene encodes a member of a family of candidate taste receptors that are members of the G protein-coupled receptor superfamily and that are specifically expressed by taste receptor cells of the tongue and palate epithelia. These apparently intronless genes encode a 7-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered with another 3 candidate taste receptor genes in chromosome 7 and is genetically linked to loci that influence bitter perception. [provided by RefSeq, Jul 2008]

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
• Leigh syndrome

  Inheritance: AD Classification: LIMITED Submitted by: ClinGen

ACMG classification
