Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.1978A>G (p.R660G) alteration is located in exon 16 (coding exon 15) of the SRBD1 gene. This alteration results from a A to G substitution at nucleotide position 1978, causing the arginine (R) at amino acid position 660 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
