The c.410G>T (p.R137L) alteration is located in exon 4 (coding exon 3) of the CAPSL gene. This alteration results from a G to T substitution at nucleotide position 410, causing the arginine (R) at amino acid position 137 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
