Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 27, 2023The c.686T>A (p.L229Q) alteration is located in exon 6 (coding exon 6) of the GRTP1 gene. This alteration results from a T to A substitution at nucleotide position 686, causing the leucine (L) at amino acid position 229 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
