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 GeneticsOct 06, 2021The c.961G>T (p.A321S) 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 961, causing the alanine (A) at amino acid position 321 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
