Autosomal dominant
Description

Age of Onset Details
7-68 (one family)

Locus

Details
TTTTA repeat expansions and TTTCA repeat insertions in intron 4 of the RAI1 gene that co-segregated with disease status in a single large family from Mali2 . Ten affected individuals were studied. Both TTTTA and TTTCA motifs were observed in all eight of the affected individuals with spanning reads, with allele sizes in the range: (TTTTA)278-773(TTTCA)9-334. A single individual was observed with additional motifs and interruptions in one allele with the structure: (TTTTA)exp(GGGGT)ins(GGGAT)ins(TTTCA)ins. TTTCA repeats were absent in 200 Malian controls, who had alleles in the range: (TTTCA)16-20. Reviewed in1 . It is uncertain if expansions at both the TTTTA and TTTCA motifs, or only the TTTCA motif are required for pathogogenicity. The pathogenic range in STRchive is for the TTTCA motif only. Note: locus is partially deleted in T2T reference genome
