The c.562C>A (p.L188I) alteration is located in exon 5 (coding exon 4) of the CDC37L1 gene. This alteration results from a C to A substitution at nucleotide position 562, causing the leucine (L) at amino acid position 188 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
