Added comment: PMID:38422122 reported the identification of 10 individuals from seven kindreds from four different ethnicities with biallelic PTCRA variants (homozygous in five kindreds and compound heterozygous in two kindreds).

Six of these 10 patients were clinically asymptomatic at their most recent evaluation, while other four patients displayed infection, lymphoproliferation, and/or autoimmunity with an onset during their teens or in adulthood. One of these patients died from SARS-CoV-2 pneumonia at the age of 24 years. Patient 9 had a small thymus on MRI at the age of 2 years, whereas P5 and P6 had no visible thymus at the ages of 13 and 8 years, respectively. Three of the nine patients with pLOF PTCRA variants tested were found to produce autoantibodies, several of which were associated with clinical manifestations. Anti-thyroid autoantibodies and/or clinically overt thyroiditis were found in three of the nine patients. P7, who suffered from recurrent herpes infections, had autoantibodies against type I interferons.

Two of those identified variants are hypomorphic and are associated with autoimmunity. In addition, there is extensive functional and epidemiological data available.
