Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 17, 2022 | The c.803G>A (p.R268Q) alteration is located in exon 10 (coding exon 9) of the HCLS1 gene. This alteration results from a G to A substitution at nucleotide position 803, causing the arginine (R) at amino acid position 268 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
