Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2024The c.809C>T (p.S270L) alteration is located in exon 6 (coding exon 6) of the RPRD1B gene. This alteration results from a C to T substitution at nucleotide position 809, causing the serine (S) at amino acid position 270 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
