The c.544A>T (p.R182W) alteration is located in exon 4 (coding exon 4) of the TMEM202 gene. This alteration results from a A to T substitution at nucleotide position 544, causing the arginine (R) at amino acid position 182 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
