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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2024The c.1330G>A (p.V444I) alteration is located in exon 6 (coding exon 4) of the MYNN gene. This alteration results from a G to A substitution at nucleotide position 1330, causing the valine (V) at amino acid position 444 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
