Mar 31, 2022

The c.385A>G (p.I129V) alteration is located in exon 7 (coding exon 5) of the SAR1A gene. This alteration results from a A to G substitution at nucleotide position 385, causing the isoleucine (I) at amino acid position 129 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
