Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 11, 2022The c.178C>T (p.H60Y) alteration is located in exon 4 (coding exon 3) of the KRBA1 gene. This alteration results from a C to T substitution at nucleotide position 178, causing the histidine (H) at amino acid position 60 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
