Genes affected

SRPRA (HGNC:11307): (SRP receptor subunit alpha) The gene encodes a subunit of the endoplasmic reticulum signal recognition particle receptor that, in conjunction with the signal recognition particle, is involved in the targeting and translocation of signal sequence tagged secretory and membrane proteins across the endoplasmic reticulum. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]

Collection Method: clinical testing

The c.736C>T (p.R246W) alteration is located in exon 6 (coding exon 6) of the SRPRA gene. This alteration results from a C to T substitution at nucleotide position 736, causing the arginine (R) at amino acid position 246 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
