Genes affected
MYO19 (HGNC:26234): (myosin XIX) Enables actin binding activity. Involved in regulation of cytokinesis and regulation of mitochondrial fission. Acts upstream of or within mitochondrion migration along actin filament. Located in cytosol and mitochondrial outer membrane. [provided by Alliance of Genome Resources, Apr 2022]
ZNHIT3 (HGNC:12309): (zinc finger HIT-type containing 3) Predicted to enable thyroid hormone receptor binding activity. Predicted to be involved in box C/D snoRNP assembly; maturation of LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA); and snoRNA localization. Located in cytoplasm and nucleus. Implicated in PEHO syndrome. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.2426C>G (p.A809G) alteration is located in exon 24 (coding exon 22) of the MYO19 gene. This alteration results from a C to G substitution at nucleotide position 2426, causing the alanine (A) at amino acid position 809 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
