Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.688G>C (p.A230P) alteration is located in exon 5 (coding exon 4) of the TMEM248 gene. This alteration results from a G to C substitution at nucleotide position 688, causing the alanine (A) at amino acid position 230 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
