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 GeneticsSep 22, 2023The c.1019C>G (p.T340S) alteration is located in exon 4 (coding exon 2) of the MYNN gene. This alteration results from a C to G substitution at nucleotide position 1019, causing the threonine (T) at amino acid position 340 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
