Genes affected
RPH3AL (HGNC:10296): (rabphilin 3A like (without C2 domains)) The protein encoded by this gene plays a direct regulatory role in calcium-ion-dependent exocytosis in both endocrine and exocrine cells and plays a key role in insulin secretion by pancreatic cells. This gene is likely a tumor suppressor. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jun 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.688G>T (p.V230F) alteration is located in exon 8 (coding exon 6) of the RPH3AL gene. This alteration results from a G to T substitution at nucleotide position 688, causing the valine (V) at amino acid position 230 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
