Genes affected
MYO1B (HGNC:7596): (myosin IB) Enables ATP binding activity; actin filament binding activity; and microfilament motor activity. Involved in actin filament organization and post-Golgi vesicle-mediated transport. Located in several cellular components, including actin filament; endosome; and perinuclear region of cytoplasm. Colocalizes with trans-Golgi network membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2024The c.1706C>T (p.T569I) alteration is located in exon 17 (coding exon 16) of the MYO1B gene. This alteration results from a C to T substitution at nucleotide position 1706, causing the threonine (T) at amino acid position 569 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
