Ambry Genetics

Jun 16, 2024

The c.335G>A (p.R112H) alteration is located in exon 2 (coding exon 2) of the SNED1 gene. This alteration results from a G to A substitution at nucleotide position 335, causing the arginine (R) at amino acid position 112 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
