Collection Method:clinical testing

The c.157G>C (p.D53H) alteration is located in exon 2 (coding exon 2) of the LSMEM2 gene. This alteration results from a G to C substitution at nucleotide position 157, causing the aspartic acid (D) at amino acid position 53 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
