Genes affected
MYO18A (HGNC:31104): (myosin XVIIIA) The protein encoded by this gene can bind GOLPH3, linking the Golgi to the cytoskeleton and influencing Golgi membrane trafficking. The encoded protein is also part of a complex that assembles lamellar actomyosin bundles and may be required for cell migration. [provided by RefSeq, Oct 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.7T>C (p.S3P) alteration is located in exon 1 (coding exon 1) of the TIAF1 gene. This alteration results from a T to C substitution at nucleotide position 7, causing the serine (S) at amino acid position 3 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
