Genes affected

MEOX2 (HGNC:7014): (mesenchyme homeobox 2) This gene encodes a member of a subfamily of non-clustered, diverged, antennapedia-like homeobox-containing genes. The encoded protein may play a role in the regulation of vertebrate limb myogenesis. Mutations in the related mouse protein may be associated with craniofacial and/or skeletal abnormalities, in addition to neurovascular dysfunction observed in Alzheimer's disease.

The c.149T>C (p.I50T) alteration is located in exon 1 (coding exon 1) of the MEOX2 gene. This alteration results from a T to C substitution at nucleotide position 149, causing the isoleucine (I) at amino acid position 50 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
