Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 31, 2024 | The c.760A>G (p.I254V) alteration is located in exon 9 (coding exon 8) of the MEIOB gene. This alteration results from a A to G substitution at nucleotide position 760, causing the isoleucine (I) at amino acid position 254 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
