Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.965G>A (p.R322Q) alteration is located in exon 7 (coding exon 7) of the GSG1L gene. This alteration results from a G to A substitution at nucleotide position 965, causing the arginine (R) at amino acid position 322 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
