The c.1039C>T (p.H347Y) alteration is located in exon 9 (coding exon 8) of the TMEM184B gene. This alteration results from a C to T substitution at nucleotide position 1039, causing the histidine (H) at amino acid position 347 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
