Genes affected

RHBDL2 (HGNC:16083): (rhomboid like 2) The protein encoded by this gene is a member of the rhomboid family of integral membrane proteins. This family contains proteins that are related to Drosophila rhomboid protein. Members of this family are found in both prokaryotes and eukaryotes and are thought to function as intramembrane serine proteases. The encoded protein is thought to release soluble growth factors by proteolytic cleavage of certain membrane-bound substrates, including ephrin B2 and ephrin B3. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2015]

The c.14A>G (p.H5R) alteration is located in exon 2 (coding exon 1) of the RHBDL2 gene. This alteration results from a A to G substitution at nucleotide position 14, causing the histidine (H) at amino acid position 5 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
