Genes affected

EBF2 (HGNC:19090): (EBF transcription factor 2) The protein encoded by this gene belongs to the COE (Collier/Olf/EBF) family of non-basic, helix-loop-helix transcription factors that have a well conserved DNA binding domain. The COE family proteins play an important role in variety of developmental processes. Studies in mouse suggest that this gene may be involved in the differentiation of osteoblasts.

The c.1258G>A (p.A420T) alteration is located in exon 13 (coding exon 13) of the EBF2 gene. This alteration results from a G to A substitution at nucleotide position 1258, causing the alanine (A) at amino acid position 420 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
