Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2022The c.41C>A (p.A14E) alteration is located in exon 1 (coding exon 1) of the SRXN1 gene. This alteration results from a C to A substitution at nucleotide position 41, causing the alanine (A) at amino acid position 14 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
