The c.454C>A (p.R152S) alteration is located in exon 2 (coding exon 2) of the TMEM151B gene. This alteration results from a C to A substitution at nucleotide position 454, causing the arginine (R) at amino acid position 152 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
