Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2023The c.136C>T (p.P46S) alteration is located in exon 1 (coding exon 1) of the MXRA7 gene. This alteration results from a C to T substitution at nucleotide position 136, causing the proline (P) at amino acid position 46 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
