The c.139T>A (p.Y47N) alteration is located in exon 2 (coding exon 1) of the TMEM45A gene. This alteration results from a T to A substitution at nucleotide position 139, causing the tyrosine (Y) at amino acid position 47 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
