Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 21, 2023 | The c.1229C>T (p.S410L) alteration is located in exon 12 (coding exon 11) of the CHAF1B gene. This alteration results from a C to T substitution at nucleotide position 1229, causing the serine (S) at amino acid position 410 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
