Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.388C>T (p.P130S) alteration is located in exon 3 (coding exon 2) of the HYKK gene. This alteration results from a C to T substitution at nucleotide position 388, causing the proline (P) at amino acid position 130 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
