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.3143C>G (p.P1048R) alteration is located in exon 23 (coding exon 22) of the SEC31B gene. This alteration results from a C to G substitution at nucleotide position 3143, causing the proline (P) at amino acid position 1048 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
