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.3139C>A (p.P1047T) alteration is located in exon 23 (coding exon 22) of the SEC31B gene. This alteration results from a C to A substitution at nucleotide position 3139, causing the proline (P) at amino acid position 1047 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
