Genes affected
STX4 (HGNC:11439): (syntaxin 4) Enables sphingomyelin phosphodiesterase activator activity. Involved in several processes, including cornified envelope assembly; positive regulation of immune effector process; and positive regulation of protein localization. Located in several cellular components, including basolateral plasma membrane; cytoplasmic vesicle; and lamellipodium. Part of SNARE complex. Is active in glutamatergic synapse and postsynapse.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.289A>G (p.I97V) alteration is located in exon 4 (coding exon 4) of the STX4 gene. This alteration results from a A to G substitution at nucleotide position 289, causing the isoleucine (I) at amino acid position 97 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
