The c.335A>G (p.D112G) alteration is located in exon 3 (coding exon 3) of the CR1L gene. This alteration results from a A to G substitution at nucleotide position 335, causing the aspartic acid (D) at amino acid position 112 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
