Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2024The c.977G>A (p.R326H) alteration is located in exon 9 (coding exon 9) of the RHBDL3 gene. This alteration results from a G to A substitution at nucleotide position 977, causing the arginine (R) at amino acid position 326 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
