Genes affected

SEC31B (HGNC:23197): (SEC31 homolog B, COPII coat complex component) This gene encodes a protein of unknown function. The protein has moderate similarity to rat VAP1 protein which is an endosomal membrane-associated protein, containing a putative Ca2+/calmodulin-dependent kinase II phosphorylation site.

The c.3496A>C (p.I1166L) alteration is located in exon 26 (coding exon 25) of the SEC31B gene. This alteration results from a A to C substitution at nucleotide position 3496, causing the isoleucine (I) at amino acid position 1166 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
