Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2021The c.1874G>A (p.C625Y) alteration is located in exon 15 (coding exon 14) of the SRBD1 gene. This alteration results from a G to A substitution at nucleotide position 1874, causing the cysteine (C) at amino acid position 625 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
