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.

The c.173A>G (p.K58R) alteration is located in exon 3 (coding exon 3) of the STX4 gene. This alteration results from a A to G substitution at nucleotide position 173, causing the lysine (K) at amino acid position 58 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
