The c.570G>T (p.R190S) alteration is located in exon 4 (coding exon 1) of the R3HCC1L gene. This alteration results from a G to T substitution at nucleotide position 570, causing the arginine (R) at amino acid position 190 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
