Description

O'Driscoll et al. (2001) identified a 2440C-T transition of the LIG4 gene in 2 sibs (patients 2303 and 2304) with LIG4 syndrome (606593). The mutation resulted in an arg814-to-ter substitution (R814X). The patients were compound heterozygotes; the other allele had the R580X mutation (601837.0001). O'Driscoll et al. (2001) also identified the arg814-to-ter mutation in another patient with LIG4 syndrome (patient 99P0149) who was a compound heterozygote; the other LIG4 mutation in this patient was gly469 to glu (601837.0003).

In a 4-year-old boy with acute T-cell leukemia and a facial gestalt reminiscent of Nijmegen breakage syndrome, Ben-Omran et al. (2005) identified homozygosity for R814X in the LIG4 gene.

Description

This heterozygous variant in the LIG4 gene (autosomal recessive transmission) was identified in a twin pair (one male and one female patient) with extreme growth delay, who also harbours another variant in the LIG4 gene (compound heterozygosity)
