Genes affected

APCDD1 (HGNC:15718): (APC down-regulated 1) This locus encodes an inhibitor of the Wnt signaling pathway. Mutations at this locus have been associated with hereditary hypotrichosis simplex. Increased expression of this gene may also be associated with colorectal carcinogenesis.[provided by RefSeq, Sep 2010]

APCDD1 Gene-Disease associations (from GenCC):

• hypotrichosis 1

  Inheritance: AD Classification: STRONG, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), G2P
• hypotrichosis simplex

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ENSG00000301982 (HGNC:):

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).
