Genes affected
APOF (HGNC:615): (apolipoprotein F) The product of this gene is one of the minor apolipoproteins found in plasma. This protein forms complexes with lipoproteins and may be involved in transport and/or esterification of cholesterol. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2023The c.698C>T (p.S233L) alteration is located in exon 2 (coding exon 2) of the APOF gene. This alteration results from a C to T substitution at nucleotide position 698, causing the serine (S) at amino acid position 233 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
