The c.580T>A (p.Y194N) alteration is located in exon 3 (coding exon 3) of the TMEM151B gene. This alteration results from a T to A substitution at nucleotide position 580, causing the tyrosine (Y) at amino acid position 194 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
