Ambry Genetics

Oct 04, 2022

The c.830G>T (p.S277I) alteration is located in exon 1 (coding exon 1) of the RABGAP1L gene. This alteration results from a G to T substitution at nucleotide position 830, causing the serine (S) at amino acid position 277 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
