The c.226G>T (p.V76L) alteration is located in exon 2 (coding exon 1) of the CRISPLD1 gene. This alteration results from a G to T substitution at nucleotide position 226, causing the valine (V) at amino acid position 76 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
