Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.238T>G (p.S80A) alteration is located in exon 1 (coding exon 1) of the RABGAP1L gene. This alteration results from a T to G substitution at nucleotide position 238, causing the serine (S) at amino acid position 80 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
