Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.34C>G (p.Q12E) alteration is located in exon 1 (coding exon 1) of the TMEM184C gene. This alteration results from a C to G substitution at nucleotide position 34, causing the glutamine (Q) at amino acid position 12 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
