RCV000678346 | SCV000804410 | likely pathogenic | Pitt-Hopkins syndrome | 2017-03-29 | criteria provided, single submitter | provider interpretation | This 6 year old male with global developmental delays, hypotonia, cryptorchidism, and large stature was found to carry a missense variant in the TCF4 gene. At the date of report, he had no history of seizure activity or hypervenitlation, but he was noted to have dysmorphic features, including mild brachycephaly, narrow palpebral fissures, overfolded helices and small, pointed tragi, a single transverse palmar crease on the right hand, and a shortened transverse palmar crease on the left hand. The p.Val617Phe variant is absent from population databases and has not been reported in other individuals with Pitt-Hopkins syndrome, to our knowledge. Computational models predict the variant to be probably damaging. A variant at codon 614 has been reported previously in an individual with Pitt-Hopkins, which supports the functional importance of this region. |
