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.3278C>T (p.A1093V) alteration is located in exon 24 (coding exon 23) of the SEC31B gene. This alteration results from a C to T substitution at nucleotide position 3278, causing the alanine (A) at amino acid position 1093 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
