Genes affected

HDLBP (HGNC:4857): (high density lipoprotein binding protein) The protein encoded by this gene binds high density lipoprotein (HDL) and may function to regulate excess cholesterol levels in cells. The encoded protein also binds RNA and can induce heterochromatin formation. [provided by RefSeq, Mar 2016]

The c.2856C>G (p.I952M) alteration is located in exon 21 (coding exon 19) of the HDLBP gene. This alteration results from a C to G substitution at nucleotide position 2856, causing the isoleucine (I) at amino acid position 952 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
