Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2023The c.302G>A (p.R101H) alteration is located in exon 2 (coding exon 2) of the SRXN1 gene. This alteration results from a G to A substitution at nucleotide position 302, causing the arginine (R) at amino acid position 101 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
