Genes affected

MALRD1 (HGNC:24331): (MAM and LDL receptor class A domain containing 1) This gene encodes a conserved protein that features multiple MAM (meprin-A5-protein tyrosine phosphatase mu) and LDLR A2 (low density lipoprotein receptor A2) domains. Expression of this gene is enriched in the small intestine and is upregulated during differentiation of a human cell line that exhibits properties of intestinal epithelial cells. The encoded protein has been shown to modulate production of FGF19 in a human intestinal cell line and may regulate bile acid metabolism in the liver. A synergistic interaction between an allele of this gene and the APOE E4 allele is associated with an elevated risk of Alzheimer's disease in human patients. [provided by RefSeq, Jul 2017]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.543 is higher than 0.05.
