Genes affected

MYNN (HGNC:14955): (myoneurin) This gene encodes a member of the BTB/POZ and zinc finger domain-containing protein family that are involved in the control of gene expression. Alternative splicing results in multiple transcript variants and a pseudogene has been identified on chromosome 14. [provided by RefSeq, Jun 2010]

The c.749T>C (p.I250T) alteration is located in exon 4 (coding exon 2) of the MYNN gene. This alteration results from a T to C substitution at nucleotide position 749, causing the isoleucine (I) at amino acid position 250 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
