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]

Nov 24, 2021

The c.836C>T (p.P279L) alteration is located in exon 9 (coding exon 7) of the RPH3AL gene. This alteration results from a C to T substitution at nucleotide position 836, causing the proline (P) at amino acid position 279 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
