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]

Ambry Genetics

Feb 16, 2023

The c.257A>C (p.N86T) alteration is located in exon 3 (coding exon 1) of the MYNN gene. This alteration results from a A to C substitution at nucleotide position 257, causing the asparagine (N) at amino acid position 86 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
