Allelic frequency abroad (gnomAD [7]) 0.58% (75/12,985 Finnish individuals) 0.25% (157/62,175 European, non-Finnish individuals)b Seen in one individual (European, non-Finnish) out of 138,632
SIFTc Deleterious NA
PolyPhen-2c Possibly damaging NA
GERP conservation scored Highly conserved (5.44) Highly conserved (4.95)
Disease in literature Early Infantile Epileptic Encephalopathy-44 [2,3,4]
  1. aFunctional annotation as suggested by the Human Genome Variation Society (HGVS)
  2. bA lower frequency in other populations
  3. cSIFT and PolyPhen-2 are scores for the predicted effect of amino acid substitution on protein structure and function
  4. dThe Genomic Evolutionary Rate Profiling (GERP) framework gives a measure of evolutionary conservation based on the alignment of sequences from 29 mammalian species
