No somatic CTNNB1 mutations were identified, but the disease-causing c.451G&amp;gt;C KCNJ5 mutation was found in two individuals with partial and no GnRH responses and an individual showing a positive response to LH. Two additional somatic pathogenic mutations, CACNA1D c.776T&amp;gt;A and ATP1A1 c.311T&amp;gt;G, were identified in two patients with no GnRH responses.
