Collection Method: clinical testing

The c.112G>C (p.V38L) alteration is located in exon 1 (coding exon 1) of the CRELD2 gene. This alteration results from a G to C substitution at nucleotide position 112, causing the valine (V) at amino acid position 38 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
