Genes affected

DTHD1 (HGNC:37261): (death domain containing 1) This gene encodes a protein which contains a death domain. Death domain-containing proteins function in signaling pathways and formation of signaling complexes, as well as the apoptosis pathway. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2012]

DTHD1 Gene-Disease associations (from GenCC):

• LCAT deficiency

  Inheritance: AR Classification: LIMITED Submitted by: Franklin by Genoox

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
