| Chromosomal Location |
2q23.1 |
| Allelic Variant 1 |
heterozygous deletion; |
| Identified Mutation |
713kb DEL at 2q22.3-q23.1; Microdeletion: 713 kb loss of genomic material from the long arm of chromosome 2, at 2q22.3-q23.1. The aberrant region contains 3 known genes, including an isoform of MBD5. |
| Remarks |
Clinically affected; dysmorphic features include: relatively prominent frontal area on head, small nasal bridge, diminutive nose, mild sandal gap in the right lower foot; developmental delay; motor delay; not able to walk independently at 18 months; heterozygous de novo 713 kb deletion in the MBD5 (methyl-CpG binding domain protein 5) gene confirmed by chromosomal microarray, real-time PCR, and FISH; the aberrant region on the long arm of chromosome 2 contains 3 known genes (an isoform of MBD5, ORC4L and ACVR2A); subject receives physical and speech therapy; lymphoblast is GM23711; unaffected mother is GM24586 fibroblast/GM23712 lymphoblast and unaffected father is GM24587 fibroblast/GM23713 lymphoblast. |
