605314.0002; BRACHYDACTYLY-MENTAL RETARDATION SYNDROME |
| Identified Mutation |
65-BP DEL, NT490+56; In a 16-year-old Caucasian girl with brachydactyly-mental retardation syndrome (BDMR; 600430), Williams et al. (Am J Hum Genet 87:219-28, 2010) identified a heterozygous de novo 65-bp deletion (490+56_121del65) in intron 5 of the HDAC4 gene, which was predicted to alter the splicing of exons 5 and 6. She had dysmorphic features, brachydactyly type E, psychomotor retardation, and severe behavioral abnormalities. |
| Remarks |
Clinically affected; mental retardation; behavioral problems (agression and self-injurious behavior like skin picking); obesity; mild type E brachydactyly; developmental delay; motor delay; language impairment; sleeping difficulties; decreased sensitivity to pain; short stature; broad face; upslanting eyes; broad, not upturned nose; small chin; narrow palpebral fissures; constipation; hypermobility; bitemporal narrowing; dental anomalies; donor subject is heterozygous for a de novo 65 bp deletion in intron 5 of the HDAC4 gene (490+56_121del65) predicted to alter the splicing of exons 5 and 6 |
