Genes affected
PTCHD1 (HGNC:26392): (patched domain containing 1) This gene encodes a membrane protein with a patched domain. The encoded protein is similar to Drosophila proteins which act as receptors for the morphogen sonic hedgehog. Deletions in this gene, which is located on the X chromosome, are associated with intellectual disability and autism (PMID: 21091464, PMID: 20844286). [provided by RefSeq, Aug 2011]
PTCHD1 Gene-Disease associations (from GenCC):
  • autism, susceptibility to, X-linked 4
    Inheritance: XL Classification: DEFINITIVE, STRONG Submitted by: Laboratory for Molecular Medicine, Labcorp Genetics (formerly Invitae), G2P
  • non-syndromic X-linked intellectual disability

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1110C>G (p.D370E) alteration is located in exon 3 (coding exon 3) of the PTCHD1 gene. This alteration results from a C to G substitution at nucleotide position 1110, causing the aspartic acid (D) at amino acid position 370 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
