Collection Method: clinical testing

The c.1120T>C (p.Y374H) alteration is located in exon 9 (coding exon 8) of the TMEM184A gene. This alteration results from a T to C substitution at nucleotide position 1120, causing the tyrosine (Y) at amino acid position 374 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
