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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 26, 2024The c.363G>T (p.Q121H) alteration is located in exon 2 (coding exon 2) of the APOF gene. This alteration results from a G to T substitution at nucleotide position 363, causing the glutamine (Q) at amino acid position 121 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
