GeneDx RCV000482525 SCV000571705 likely pathogenic not provided 2016-09-30 criteria provided, single submitter clinical testing The c.1394_1397delTCAA variant in the EIF2S3 gene has been reported previously in a family segregating a form of syndromic X-linked intellectual disability characterized by neonatal hypoglycemia, severe microcephaly, developmental delay, micropenis, epileptic seizures and early death (Moortgat et al., 2016). In this family, the c.1394_1397delTCAA variant was present in three obligate carrier female relatives and absent in three healthy male relatives, however, no affected male relatives were available for testing (Moorgat et al., 2016). The c.1394_1397delTCAA variant causes a frameshift starting with codon Isoleucine 465, changes this amino acid to a Serine residue, and creates a premature Stop codon at position 4 of the new reading frame, denoted p.Ile465SerfsX4. This variant is predicted to cause loss of normal protein function through protein truncation. The c.1394_1397delTCAA variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Therefore, we interpret c.1394_1397delTCAA variant as a likely pathogenic variant.
