Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 09, 2022 | The c.385C>T (p.R129C) alteration is located in exon 4 (coding exon 4) of the MGRN1 gene. This alteration results from a C to T substitution at nucleotide position 385, causing the arginine (R) at amino acid position 129 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
