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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 21, 2024The c.3508G>A (p.V1170I) alteration is located in exon 26 (coding exon 25) of the SEC31B gene. This alteration results from a G to A substitution at nucleotide position 3508, causing the valine (V) at amino acid position 1170 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
