Genes affected
GPR22 (HGNC:4477): (G protein-coupled receptor 22) This gene is a member of the G-protein coupled receptor 1 family and encodes a multi-pass membrane protein. [provided by RefSeq, Jul 2008]
COG5 (HGNC:14857): (component of oligomeric golgi complex 5) The protein encoded by this gene is one of eight proteins (Cog1-8) which form a Golgi-localized complex (COG) required for normal Golgi morphology and function. The encoded protein is organized with conserved oligomeric Golgi complex components 6, 7 and 8 into a sub-complex referred to as lobe B. Alternative splicing results in multiple transcript variants. Mutations in this gene result in congenital disorder of glycosylation type 2I.[provided by RefSeq, Jan 2011]

The c.191T>C (p.V64A) alteration is located in exon 3 (coding exon 1) of the GPR22 gene. This alteration results from a T to C substitution at nucleotide position 191, causing the valine (V) at amino acid position 64 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
