Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 27, 2023 | The c.154C>T (p.L52F) alteration is located in exon 3 (coding exon 3) of the ARFGEF2 gene. This alteration results from a C to T substitution at nucleotide position 154, causing the leucine (L) at amino acid position 52 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
