Description

Our laboratory reported dual molecular diagnoses in PTPN11 (NM_002834.3, c.179G>T) and SHH (NM_000193.2, c.1284delC) in one individual with reported features of global developmental delay, hearing loss, hypotonia, hypertonia/spasticity, possible seizures, dysmorphic features (low frontal hairline, frontal bossing, deep set eye, downslanting palpebral fissures, broad based nose, upturned nasal tip), short 5th fingers, macrocephaly, structural brain abnormalities (agenesis of corpus callosum, large post interhemispheric cyst), possible cortical vision impairment, and an atrial septal defect.

Description

The c.179G>T;p.(Gly60Val) missense variant has been observed in affected individual(s) and ClinVar contains an entry for this variant (ClinVar ID: ClinVar ID: 55797; PMID: 29907801; 18470943; 18701506) -.PS4. Well-established in vitro or in vivo functional studies support a damaging effect on the gene or gene product (PMID: 30375388) - PMID: 30375388 The variant is located in a mutational hot spot and/or critical and well-established functional domain (SH2 domain) - PM1. This variant is not present in population databases (rs397507509 , gnomAD; ABraOM no frequency - http://abraom.ib.usp.br/) - PM2. Pathogenic missense variant in this residue have been reported (Clinvar ID:40493; 987743; 40490; 372590; 41442) - PM5. Missense variant in PTPN11 that has a low rate of benign missense variation and in which missense variants are a common mechanism of disease - PP2. Multiple lines of computational evidence support a deleterious effect on the gene or gene product - PP3. In summary, the currently available evidence indicates that the variant is pathogenic.
