Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2024The c.505C>T (p.P169S) alteration is located in exon 6 (coding exon 5) of the KRBA1 gene. This alteration results from a C to T substitution at nucleotide position 505, causing the proline (P) at amino acid position 169 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
