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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.3044C>T (p.P1015L) alteration is located in exon 23 (coding exon 22) of the SEC31B gene. This alteration results from a C to T substitution at nucleotide position 3044, causing the proline (P) at amino acid position 1015 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
