The c.112G>C (p.D38H) alteration is located in exon 4 (coding exon 3) of the N4BP2L2 gene. This alteration results from a G to C substitution at nucleotide position 112, causing the aspartic acid (D) at amino acid position 38 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
