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

Dec 09, 2023

The c.676G>T (p.V226F) alteration is located in exon 4 (coding exon 2) of the MYNN gene. This alteration results from a G to T substitution at nucleotide position 676, causing the valine (V) at amino acid position 226 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
