Collection Method: clinical testing

The c.1886G>T (p.R629L) alteration is located in exon 21 (coding exon 21) of the ABLIM2 gene. This alteration results from a G to T substitution at nucleotide position 1886, causing the arginine (R) at amino acid position 629 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
