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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2023The c.79C>T (p.L27F) alteration is located in exon 2 (coding exon 2) of the APCDD1 gene. This alteration results from a C to T substitution at nucleotide position 79, causing the leucine (L) at amino acid position 27 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
